TrumpRx vs GoodRx vs Cost Plus Drugs: Which Saves You More? (2026)

Three Approaches to Cheaper Drugs

Americans filled over 6.7 billion prescriptions in 2025, and out-of-pocket costs remain a top concern. While Medicare's new negotiated prices help some beneficiaries, millions of uninsured and underinsured patients depend on discount programs to afford their medications. TrumpRx, GoodRx, and Cost Plus Drugs each attack the pricing problem differently.

TrumpRx: Most-Favored-Nation Pricing on Select Drugs

Launched in February 2026 through an executive order, TrumpRx negotiated prices with five pharmaceutical manufacturers to offer 43 commonly prescribed drugs at most-favored-nation (MFN) pricing—meaning Americans pay no more than the lowest price charged in comparable countries. The program uses GoodRx's existing data backend and pharmacy network to power its discount cards.

• Coverage: 43 drugs from 5 manufacturers (Pfizer, Johnson & Johnson, Merck, Bristol-Myers Squibb, and Novartis)
• Pricing model: MFN pricing tied to international reference prices
• How to use: Free discount card, no enrollment required
• Key limitation: Cash-pay only—purchases do not count toward your insurance deductible or out-of-pocket maximum

For the specific drugs it covers, TrumpRx can offer significant savings. But the narrow formulary of 43 drugs means most patients will still need another option for the rest of their medications.

GoodRx: The Broadest Coverage

GoodRx remains the largest drug discount platform in the United States. With 23.5 million monthly active users and coupon acceptance at more than 70,000 pharmacies, it covers virtually every FDA-approved medication.

• Coverage: Thousands of drugs—generics and brands
• Pricing model: Negotiated rates from multiple PBMs; prices vary by pharmacy
• Free tier: Basic coupons at no cost
• Gold subscription: $9.99/month for deeper discounts on 1,000+ drugs, plus family coverage
• Pharmacy access: 70,000+ locations including CVS, Walgreens, Walmart, and independent pharmacies

GoodRx's greatest strength is breadth. For popular generics like Ozempic or diabetes medications, GoodRx lets you compare prices across every nearby pharmacy in seconds. The tradeoff: GoodRx is a coupon aggregator, not a pharmacy, so prices are less transparent and can fluctuate.

Cost Plus Drugs: Transparent Cost-Plus Pricing

Mark Cuban's Cost Plus Drugs takes the most radical approach to drug pricing transparency. Every medication lists its manufacturer cost, and the company adds a flat 15% markup plus a $5 pharmacy fee plus $5 shipping. That's it—no PBMs, no hidden fees, no price games.

• Coverage: 2,200+ medications, primarily generics
• Pricing model: Manufacturer cost + 15% + $5 pharmacist fee + $5 shipping
• Pharmacy type: Mail-order only (ships to your door)
• Insurance: Not needed—cash-pay at transparent prices

Cost Plus Drugs excels for patients on chronic generic medications. A 90-day supply often costs a fraction of what retail pharmacies charge. The limitation is no same-day pickup and a smaller formulary than GoodRx.

Side-by-Side Comparison

When to Use Each Program

Use TrumpRx when:

• Your medication is one of the 43 covered drugs
• You want same-day pickup at a retail pharmacy
• The MFN price beats both GoodRx coupons and Cost Plus pricing

Use GoodRx when:

• Your drug is not covered by TrumpRx or Cost Plus
• You want to compare prices across multiple pharmacies near you
• You need a brand-name drug that Cost Plus doesn't carry
• You take many different medications and want one tool to manage all of them

Use Cost Plus Drugs when:

• You take a chronic generic medication (statins, blood pressure, metformin, etc.)
• You don't need same-day pickup—a 90-day mail-order supply works
• You value transparent pricing and want to see exactly what you're paying for
• You're uninsured or your insurance copay is higher than the cash price

What About Medicare Negotiated Prices?

If you're on Medicare Part D, discount cards are largely irrelevant for your covered medications. The Inflation Reduction Act gave Medicare the power to negotiate prices directly with drug manufacturers starting in 2026. These negotiated prices apply automatically at the pharmacy—no coupon or card needed.

Medicare's negotiated prices cover a growing list of high-cost drugs and are completely separate from TrumpRx, GoodRx, or Cost Plus. If your drug is on the IRA negotiated list, that price is almost certainly your best option. For drugs not on the negotiated list, Medicare Part D's new $2,000 annual out-of-pocket cap (effective 2025) provides an additional backstop.

The Bottom Line

No single program is best for every patient. The smartest strategy is to check all three before filling any prescription:

1. Check TrumpRx first if your drug is on its 43-drug list—MFN pricing may beat everything else
2. Compare on GoodRx to see retail coupon prices at pharmacies near you
3. Look up Cost Plus Drugs for the transparent cash price, especially on generics
4. Check your insurance formulary—sometimes your copay is still the cheapest option

Drug pricing in America remains fragmented and confusing by design. These programs exist because the system fails patients on price transparency. Use all the tools available to you, and look up any medication on DrugPrice to see the full cost picture before you fill.
