GoodRx vs. RxSaver vs. SingleCare: Which Pharmacy Discount Card Wins in 2026?

Pharmacy discount cards are one of the most underused tools in personal finance. They’re free to sign up, work without insurance, and routinely beat the cash price and even some insurance copays for the same generic prescription. The catch: no single card wins at every pharmacy for every drug. The right tactic is to compare per prescription, every time.

Here’s the 2026 breakdown of the three biggest players.

GoodRx

The largest and most established pharmacy discount network. Free to use; paid “Gold” tier exists for additional savings.

Strengths:

• Largest pharmacy network. Accepted at virtually every major chain (CVS, Walgreens, Rite Aid, Walmart, Kroger, Publix, Costco, Sam’s, plus most independents).
• Most extensive drug database. Covers nearly every commonly prescribed medication, both generic and brand name.
• Brand recognition. Most pharmacists know GoodRx and process it without questions.
• GoodRx app and website are well-designed; price comparisons across nearby pharmacies are easy to view.
• GoodRx Gold ($9.99/month or $19.99/month for family) offers deeper discounts on certain drugs, particularly long-term maintenance medications.

Weaknesses:

• Not always the cheapest — SingleCare or RxSaver often beats GoodRx on specific drugs.
• The negotiated prices are with pharmacy benefit managers (PBMs) — there’s a markup layered in.
• Cash prices at Costco are sometimes cheaper than GoodRx prices even for non-Costco members.

Best for: First check on every prescription. The “default” pharmacy discount card.

SingleCare

A direct competitor to GoodRx that’s grown rapidly over the last several years.

Strengths:

• Often beats GoodRx on specific common generics. Particularly strong on amoxicillin, sertraline, metformin, atorvastatin, and other high-volume drugs.
• Wide pharmacy network comparable to GoodRx.
• Simple, straightforward pricing display.
• No “Gold tier” — the public prices are the prices.

Weaknesses:

• Smaller brand recognition than GoodRx, occasionally causing pharmacist confusion at independent pharmacies.
• Smaller drug database than GoodRx for niche or specialty medications.
• App is less polished than GoodRx.

Best for: Second check on every prescription. If SingleCare beats GoodRx for your specific drug, use SingleCare.

RxSaver (by RetailMeNot)

The third major player, formerly known as Blink Health for some functions.

Strengths:

• Sometimes the cheapest on specific generics that aren’t covered well by GoodRx or SingleCare.
• Aggregates from multiple PBM networks, surfacing prices the others miss.
• Comparison tool surfaces all three competitors’ prices in some implementations.

Weaknesses:

• Smaller brand recognition than GoodRx and SingleCare.
• Pharmacist confusion is more common.
• The user experience is less smooth than GoodRx’s.

Best for: Third check on the prescriptions where the first two cards’ prices are unsatisfactory.

The strategy: compare per prescription, every time

The correct approach to pharmacy discount cards is to never assume one card is always cheapest. Tactics:

1. Open GoodRx app or website. Enter your drug name, dosage, and quantity. Note the prices across nearby pharmacies.
2. Open SingleCare. Same drug, same dosage, same quantity. Note prices.
3. Open RxSaver. Same comparison.
4. Pick the lowest result. Show that card at the pharmacy.

The 90-second comparison can be the difference between a $15 prescription and a $3 prescription. For maintenance medications you fill monthly, that’s $144/year in savings on a single drug.

The Costco specific play

Costco Pharmacy is legally required to fill prescriptions for non-members in most states. This is widely unknown.

For many generics, Costco’s cash price (no card, no insurance) beats GoodRx, SingleCare, and RxSaver. The strategy:

• Call your nearest Costco Pharmacy with your prescription details.
• Ask for the cash price.
• Compare to GoodRx and SingleCare at other pharmacies.
• Fill at whichever is cheapest — often Costco.

For Costco members, you can also use GoodRx or SingleCare at Costco for additional savings on some drugs.

The Mark Cuban Cost Plus Drug Company

A relatively new player (founded by Mark Cuban in 2022) that’s grown rapidly:

• Cost Plus Drugs (costplusdrugs.com) sells generic medications at the manufacturer cost + 15% markup + $3 pharmacist fee + $5 shipping.
• Routinely 30–90% cheaper than retail or even GoodRx for the generics they carry.
• Mail-order only — adds 3–5 days for delivery.
• Drug catalog is growing but doesn’t cover every medication.

For maintenance medications you fill regularly, Cost Plus is now often the cheapest option in the U.S. for the drugs they carry. Check their site for your specific prescriptions.

When insurance beats the cards

Despite the discount cards’ power, your insurance is sometimes the cheaper option:

• For brand-name drugs with high cash prices, your insurance copay is usually lower than the cash discount.
• For drugs that hit your insurance deductible, paying via insurance counts toward your deductible; paying via discount card doesn’t.
• For Medicare beneficiaries, the rules around discount cards vs. Medicare Part D are complex. Sometimes the card is better; sometimes Part D is. Compare.

The strategy: ask your pharmacist to run the prescription both ways — once on your insurance, once with the discount card. The pharmacist will tell you which is cheaper. Most pharmacists are happy to do this; it takes 30 seconds.

The 30-day vs. 90-day math

For maintenance medications, 90-day fills are usually substantially cheaper than three 30-day fills:

• Per-pill discount. 90-day fills are priced at a per-pill discount of 10–20% versus 30-day fills.
• One copay or one card transaction instead of three.
• Less pharmacy time.

The catch: not every prescription is authorized for 90-day refills (controlled substances, antibiotics, etc.). For chronic maintenance drugs (blood pressure, cholesterol, thyroid, diabetes), 90-day fills are almost always available and almost always cheaper.

Specific drug examples (typical, 2026)

These prices fluctuate constantly; verify on the apps before purchasing.

• Atorvastatin 20mg, 30 tablets: GoodRx ~$8, SingleCare ~$6, Cost Plus Drugs ~$3.50.
• Metformin 500mg, 60 tablets: GoodRx ~$7, SingleCare ~$5, Cost Plus Drugs ~$3.
• Lisinopril 10mg, 30 tablets: GoodRx ~$4, SingleCare ~$4, Cost Plus Drugs ~$3.
• Sertraline 50mg, 30 tablets: GoodRx ~$10, SingleCare ~$7, Cost Plus Drugs ~$4.
• Amoxicillin 500mg, 30 capsules: GoodRx ~$6, SingleCare ~$5, Cost Plus Drugs ~$3.

These are illustrative. The exact prices vary by pharmacy and date.

The maintenance medication routine

For chronic medications, build a routine:

1. Initial setup: Compare GoodRx, SingleCare, Cost Plus, and your insurance. Pick the cheapest path.
2. 90-day fills if available.
3. Auto-refill at the chosen pharmacy if it’s a chain (CVS, Walgreens, Costco).
4. Re-compare every 6 months. Prices shift as PBM contracts renegotiate.

For an average household with 2–3 chronic medications, the annual savings of doing this routine vs. paying default insurance copays or pharmacy retail can be $300–900.

The Goodrx Gold question

Is GoodRx Gold ($9.99/month) worth it?

Yes if:

• You fill 2+ prescriptions per month.
• The Gold prices for your specific drugs are meaningfully below standard GoodRx.
• You can verify the savings exceed the monthly fee.

No if:

• You only fill 1–2 prescriptions occasionally.
• Cost Plus Drugs or SingleCare standard pricing already beats Gold for your drugs.
• You’re already paying low insurance copays.

Verify before subscribing. GoodRx Gold prices are visible without subscription on the GoodRx site if you toggle the comparison view.

The bottom line

Pharmacy discount cards work. The right strategy is:

1. Check GoodRx, SingleCare, Cost Plus Drugs, and your insurance for every new prescription.
2. Use the cheapest path.
3. Use Costco Pharmacy where it wins (even as a non-member).
4. Use 90-day fills for chronic medications.
5. Re-check every 6 months.

The annual savings on a typical household’s prescription budget: $400–1,200. The time investment: a few minutes per prescription. The hourly rate, calculated on the savings, is one of the highest in personal finance.
