Americans overpay for prescription drugs every year, often without realizing cheaper options exist. Three tools have become the most-cited ways to cut that cost: GoodRx, Mark Cuban's Cost Plus Drugs, and manufacturer coupons. Each works differently, applies to different drugs, and wins in different situations. This guide breaks down exactly how each one works in 2026, what the real prices look like, and which tool to reach for first.
Quick Answer: Cost Plus Drugs typically wins on generic medications through transparent cost-plus pricing. GoodRx wins on flexibility because it works at 75,000+ local pharmacies without a mail-order wait. Manufacturer coupons win on expensive brand-name drugs where they can eliminate copays entirely. The right strategy is to check all three before filling any prescription.
How Each Program Works
GoodRx
GoodRx is a free price-comparison app and website, not insurance. It tracks cash prices at more than 75,000 pharmacies nationwide and generates discount coupons tied to pharmacy benefit manager (PBM) contracts. You search for your drug, pick a nearby pharmacy, and show the coupon code at the counter. The pharmacist runs your prescription through the GoodRx discount instead of your insurance.
GoodRx does not set prices itself. Prices are negotiated between pharmacy purchasing groups and PBMs, then passed on to customers. Because different PBMs have different contracts with different pharmacies, the GoodRx price at CVS can be very different from the GoodRx price at Costco for the exact same drug.
Key facts as of 2026:
- Free to use (GoodRx Gold is a paid tier at around $9.99/month that can lower prices further)
- Works at any participating pharmacy in-person, same-day
- Savings range from 10% to 80% depending on the drug and pharmacy
- Cannot be combined with insurance in most cases — you choose one or the other
Cost Plus Drugs
Cost Plus Drugs (costplusdrugs.com) is a direct-to-consumer online pharmacy founded by Mark Cuban and physician Alex Oshmyansky. The pricing formula is public: the company's cost to acquire the drug, plus a 15% markup, plus a $5 pharmacy service fee, plus a $5.25 shipping fee per order.
Because Cost Plus manufactures some drugs and sources others directly, it cuts out the middlemen — wholesalers, PBMs, and retail pharmacy markups — that inflate prices at traditional pharmacies. The model works specifically for generic medications. Brand-name drugs are largely absent from the catalog.
Key facts as of 2026:
- Mail-order only, with 3 to 5 business day delivery
- Generic medications only (no brand names in most cases)
- No insurance needed or accepted
- Price formula is fully transparent and visible before you order
- No membership fee required
Manufacturer Coupons and Patient Assistance Programs
Drug manufacturers offer two types of cost-reduction programs that are often lumped together but work very differently.
Copay assistance cards are available from most major brand-name drug manufacturers. They function like a secondary insurance card, reducing your out-of-pocket copay to a nominal amount (often $0 to $10/month). Income limits typically do not apply. However, there is a major restriction: these cards cannot be used by anyone enrolled in Medicare, Medicaid, or other federal health programs. They work only for people with commercial insurance.
Patient Assistance Programs (PAPs) are manufacturer-run programs that provide the medication free or at very low cost to uninsured or underinsured patients who meet income requirements. Income limits vary widely. Novo Nordisk, for example, requires income at or below 200% of the Federal Poverty Level (FPL) for Ozempic and at or below 400% FPL for most other medications. Lilly Cares programs range from 300% to 500% FPL depending on the drug, per CMS guidance on patient assistance programs.
2026 Federal Poverty Level reference figures (used by most PAPs):
| Household Size | 100% FPL (2026) | 200% FPL | 400% FPL |
|---|
| 1 | $15,960 | $31,920 | $63,840 |
| 2 | $21,640 | $43,280 | $86,560 |
| 3 | $27,320 | $54,640 | $109,280 |
| 4 | $33,000 | $66,000 | $132,000 |
| 5 | $38,680 | $77,360 | $154,720 |
| 6 | $44,360 | $88,720 | $177,440 |
| 7 | $50,040 | $100,080 | $200,160 |
| 8 | $55,720 | $111,440 | $222,880 |

Real Price Examples (2026)
A dermatology cost-analysis study published in the Journal of the American Academy of Dermatology compared Cost Plus Drugs and GoodRx across a range of prescriptions. GoodRx offered the lowest price in 67.3% of cases. Cost Plus offered the lowest price in 32.7% of cases. When Cost Plus was cheaper, it was 25% cheaper on average. When GoodRx was cheaper, it was 79% cheaper on average.
What this means in practice: neither platform is universally cheaper. For common generic drugs with heavy PBM competition, GoodRx often wins because of volume-negotiated rates. For less common generics where PBMs have less leverage, Cost Plus often wins because its cost-plus formula strips out the markup entirely.
Common generics as of 2026 (approximate cash prices, 30-day supply):
| Medication | CVS/retail cash price | GoodRx (typical low) | Cost Plus Drugs |
|---|
| Metformin 500mg (60 tabs) | $15 to $25 | $4 to $8 | $3 to $5 |
| Lisinopril 10mg (30 tabs) | $15 to $20 | $4 to $9 | $3 to $6 |
| Atorvastatin 20mg (30 tabs) | $25 to $35 | $10 to $15 | $8 to $12 |
| Sertraline 100mg (30 tabs) | $20 to $30 | $6 to $12 | $5 to $9 |
| Amlodipine 5mg (30 tabs) | $12 to $20 | $4 to $7 | $3 to $5 |
Prices are estimates based on 2026 market data. Check goodrx.com and costplusdrugs.com directly for current figures before filling a prescription.
For brand-name drugs without generic alternatives, neither GoodRx nor Cost Plus Drugs will provide dramatic savings. Manufacturer copay assistance cards are the primary tool in those situations, reducing a $400/month specialty medication to $0 to $10/month for patients with commercial insurance.
How to Apply Each Program
Using GoodRx
- Go to goodrx.com or download the GoodRx app.
- Search for your medication by name, dose, and quantity.
- Compare prices at nearby pharmacies — prices vary significantly by location.
- Select the pharmacy with the best price and click "Get Free Coupon."
- Show the coupon barcode to your pharmacist. Do not run your insurance at the same time.
- Pay the discounted cash price shown on your coupon.
Documents needed: None. No registration required to access coupons.
Common reasons GoodRx does not save money:
- Your insurance copay is already lower than the GoodRx cash price
- Your drug is not covered by the PBM network at that pharmacy
- The pharmacy has opted out of GoodRx discounts
Using Cost Plus Drugs
- Visit costplusdrugs.com.
- Search for your medication by generic name.
- Verify the drug is in their catalog (not all generics are available).
- Create a free account and upload your prescription from your doctor.
- Complete your order. Shipping is $5.25 per order.
- Receive your medication by mail within 3 to 5 business days.
Documents needed: Valid prescription from a licensed prescriber.
Common reasons Cost Plus Drugs is not an option:
- The drug is brand-name only with no generic equivalent
- You need the medication the same day
- Your specific dosage or formulation is not in the catalog
- You are outside the contiguous United States
Applying for Manufacturer Patient Assistance
- Identify the drug manufacturer (listed on your prescription label or at FDA drug label database).
- Go directly to the manufacturer's patient assistance page (NeedyMeds.org aggregates many programs at needymeds.org).
- Confirm you meet the income requirement (most programs require documentation of household income at or below 200% to 500% FPL).
- Complete the application. Most require: proof of income, a prescription, proof of insurance status, and a signed provider form.
- Submit to the manufacturer's program. Approval typically takes 2 to 6 weeks.
- Approved patients receive medication by mail or a voucher for a specific pharmacy.
Documents needed:
- Proof of household income (tax return, pay stubs, or SSA award letter)
- Current prescription
- Insurance card (or documentation of no insurance)
- Photo ID
- Completed prescriber signature form
Common reasons PAP applications are denied:
- Income exceeds the program's FPL threshold
- Applicant has Medicare or Medicaid coverage for the drug
- The drug has a cheaper generic alternative available
- Application is incomplete or missing provider signature
Which Program Wins by Situation
Situation: Generic medication, no insurance
Use Cost Plus Drugs as your baseline, then check GoodRx at a local pharmacy. Compare both. For mail-order, Cost Plus usually wins. For same-day, GoodRx at Costco or Walmart often matches or beats Cost Plus after shipping is factored in.
Situation: Brand-name drug, commercial insurance, under 65
Apply for the manufacturer copay assistance card. This is almost always the cheapest option for expensive brand-name drugs when you have commercial insurance. GoodRx and Cost Plus will not compete here.
Situation: On Medicare, need help with drug costs
Manufacturer copay assistance cards are off-limits for Medicare enrollees by law. Use GoodRx (it works with Medicare Part D, and you can bypass Part D entirely for certain drugs). Also check if you qualify for the Medicare Extra Help (Low Income Subsidy) program, which reduces Part D costs based on income. Medicare.gov has the full Extra Help eligibility details.
Situation: Uninsured, brand-name drug, low income
Apply for the manufacturer's Patient Assistance Program. Most major manufacturers offer free or near-free medications to patients below 200% to 400% FPL with no insurance. Use NeedyMeds.org or the manufacturer's direct website to apply.
Situation: Unsure which is cheapest
Check all three before you fill. It takes five minutes. Prices change, and the winner on your last refill might not be the winner on your next one.
What These Programs Do Not Cover
None of these tools are insurance. They will not cover a doctor's visit, lab work, or anything beyond the drug itself.
Manufacturer copay cards cannot be used with government health programs. Using a manufacturer coupon while enrolled in Medicaid or Medicare violates federal anti-kickback law and can result in penalties for both the patient and the pharmacy.
GoodRx cannot be used simultaneously with insurance. You choose one per fill. If your insurance copay is below $20, insurance is usually cheaper. If you have hit your deductible or your copay is high, GoodRx often wins.
Your Insurance Coverage May Have Changed
If you are paying more than $20 to $30 per month for common generic medications, your current insurance coverage may not be giving you the best deal available. Medicaid covers most generic medications at very low or zero cost for eligible enrollees. ACA marketplace plans with cost-sharing reductions can dramatically lower drug costs for households below 250% of the federal poverty level.
Check your eligibility at CoveredUSA to find out if you qualify for Medicaid, a subsidized ACA plan, or Medicare Savings Programs that could reduce your prescription costs below what any discount program can offer. It takes two minutes.
Frequently Asked Questions
Which is cheaper, GoodRx or Cost Plus Drugs?
Neither wins every time. According to a 2025 study published in the Journal of the American Academy of Dermatology, GoodRx offered the lowest price in about 67% of cases, while Cost Plus Drugs was cheaper in the remaining 33%. When Cost Plus was cheaper, it averaged 25% lower. When GoodRx was cheaper, it averaged 79% lower. The gap depends on the specific drug, dosage, and local pharmacy competition. Always check both before filling.
Can I use GoodRx with Medicare?
Yes. GoodRx works with Medicare, and you can use it instead of Medicare Part D for specific medications, particularly those Part D does not cover well or at all. However, you cannot use GoodRx simultaneously with Part D. You choose one per prescription fill. Manufacturer copay assistance cards, by contrast, cannot be used at all with Medicare.
Is Cost Plus Drugs legitimate?
Yes. Cost Plus Drugs is a licensed pharmacy operating under the NABP (National Association of Boards of Pharmacy). It is co-founded by Mark Cuban and physician Alex Oshmyansky and operates as a for-profit company. As of 2026 it has its own manufacturing operations and fulfillment centers. You can verify its accreditation at nabp.pharmacy.
Do manufacturer coupons have income limits?
It depends on the type. Copay assistance cards (available to commercially insured patients) generally have no income limits. Patient Assistance Programs (which provide free or near-free medication to uninsured patients) almost always have income limits, typically 200% to 500% of the Federal Poverty Level depending on the manufacturer and specific drug.
Can I use a manufacturer coupon if I have Medicaid or Medicare?
No. Federal anti-kickback statutes prohibit using manufacturer copay coupons or discount cards when your prescription would otherwise be covered by a government health program. This applies to Medicare Part D, Medicaid, CHIP, TRICARE, and VA benefits. Violations can result in civil and criminal penalties for pharmacies and, in some cases, for patients.
What is GoodRx Gold and is it worth it?
GoodRx Gold is a paid subscription tier at approximately $9.99 per month ($19.99 for a family). It provides lower prices than the free coupons at participating pharmacies. It pays for itself if you fill several chronic medications monthly. For occasional fills, the free tier is usually sufficient.
Where can I find out if I qualify for Medicaid or ACA subsidies to reduce prescription costs?
If your household income is below 138% of the Federal Poverty Level and you live in a Medicaid expansion state, you likely qualify for Medicaid, which covers most prescriptions at little or no cost. If your income is between 100% and 400% FPL, you may qualify for ACA subsidies that lower your monthly premium and drug costs. Check your eligibility now at CoveredUSA, it takes 2 minutes.
Does Cost Plus Drugs carry brand-name drugs?
Mostly no. Cost Plus Drugs focuses on generics. Brand-name drugs without a generic equivalent are largely absent from the catalog. If your medication has no generic, use GoodRx to compare cash prices or apply directly to the manufacturer's assistance program.
