SingleCare vs GoodRx vs Cost Plus Drugs: Which Is Cheapest? (2026)

Updated June 2026·14 min read
Prices verified June 20, 2026Next review due Sep 2026
Bottom line up front: There is no single winner. Cost Plus Drugs is usually cheapest for 90-day mail-order generics because of its transparent cost-plus-15% pricing. GoodRx and SingleCare split the wins on same-day local fills and are nearly tied on common generics (the gap is typically under $1.50 per fill), with SingleCare more reliable at CVS and GoodRx covering more pharmacies and drug types. For controlled substances, brand-name drugs, and urgent fills, you need GoodRx or SingleCare, not Cost Plus. The cheapest strategy is to check all three for your exact drug and quantity, because all three are free.

On a moderately expensive generic, Cost Plus Drugs pulls ahead: $59.29 versus $78.00 at GoodRx and $74.50 at SingleCare. Illustrative snapshot, not a live quote.

SingleCare, GoodRx, and Cost Plus Drugs are the three savings paths most uninsured and high-deductible patients reach for, and they are constantly pitted against each other. The catch is that they are not the same kind of thing. Two are discount-card aggregators that get you a coupon price at a local pharmacy; one is an actual mail-order pharmacy with a published cost formula. That structural difference, not branding, is what decides which one is cheapest for you. We compared their price models, pharmacy networks, and a representative drug-price table to settle it. For the two-way deep dives, see our GoodRx vs SingleCare and GoodRx vs Cost Plus comparisons.

How each one actually works (and why it changes the price)

GoodRx: a coupon aggregator

GoodRx is free and its coupons are accepted at more than 70,000 store locations across the U.S. and its territories, per GoodRx's own site. You search a drug, pick the pharmacy with the best coupon price, and show the coupon. GoodRx earns a fee from the pharmacy benefit manager on each transaction rather than charging you. GoodRx reports users save up to 80% off retail.

The paid tier, GoodRx Gold, costs $9.99 per month for individuals and $19.99 per month for families, with a free 30-day trial, and is accepted at over 38,000 locations. Gold surfaces a second, often lower negotiated rate, but only pays off if you fill enough prescriptions monthly to clear the subscription fee.

SingleCare: a single-PBM discount card

SingleCare is free with no paid tier and no membership fee, accepted at more than 35,000 pharmacies, and advertises up to 80% off. It works with or without insurance. You can use coupons without an account, but signing up (just name, email, and date of birth) unlocks member savings, $3 off your next eligible fill, then roughly $1 in bonus savings on most subsequent fills. Because SingleCare negotiates primarily through one PBM partner, its pricing is a touch more consistent than GoodRx's aggregated rates, and it has kept a more stable relationship with CVS.

Cost Plus Drugs: an actual pharmacy with a published formula

Cost Plus Drugs is not a card, it is a mail-order pharmacy. Per its own FAQ, it prices every drug the same way: its acquisition cost, plus a 15% markup, plus a pharmacy fee (its pharmacy partners charge $5.00 to prepare and provide each prescription), plus shipping and taxes that vary by location. There is no insurance billing; it is cash-pay only, and in independent analysis its cash prices beat commercial insurance copays a large share of the time. The trade-offs: it is generics-focused, does not carry controlled substances, and is mail-only, so it is not for urgent or same-day needs.

Accuracy note (corrected June 2026): Cost Plus lists standard shipping as varying by location rather than a fixed flat fee, and current customer reports describe delivery typically taking around 5-10 business days, longer than the "3-5 days" often quoted. Plan refills ahead and set up auto-refill so you never run out.

Head-to-head price table: a representative generic basket

The table below shows a representative metro-area price snapshot for common generics, so you can see the pattern of who wins where. Treat the exact cells as illustrative, not a live quote: discount-card prices change by ZIP code and day, and Cost Plus totals depend on quantity and shipping. Always run your exact drug, dose, quantity, and pharmacy on all three before you fill. GoodRx and SingleCare figures are best local-coupon prices for a 30-day supply; Cost Plus figures are the published cost-plus total including its $5 pharmacy fee.

Imatinib 400mg$78.00$74.50$59.29Cost Plus

The pattern is consistent and it is the single most useful thing to internalize: on cheap, everyday generics the two cards win because the per-order fee on a mail-order pharmacy outweighs the markup difference. On moderately expensive generics, Cost Plus pulls ahead, sometimes dramatically, because retail pharmacies hold higher margins on drugs fewer people comparison-shop. SingleCare and GoodRx trade the top spot drug by drug, usually by pennies.

The 90-day flip: where Cost Plus wins by design

The 30-day table understates Cost Plus, because its $5 pharmacy fee is charged once per prescription regardless of supply length. Stretch the same drug to a 90-day supply and the fee is spread across three months, while the cost-plus-15% drug component stays low. For maintenance medications you take every day, ordering 90-day supplies from Cost Plus is frequently the cheapest path available anywhere, and you can consolidate multiple prescriptions to spread shipping further.

Key insight: Match the tool to the fill. Use Cost Plus for 90-day maintenance generics, and compare GoodRx and SingleCare for 30-day fills, controlled substances, brand drugs, and anything you need today.

If you are self-employed and managing healthcare costs yourself, all three belong in your toolkit, and out-of-pocket prescription costs may be tax-relevant. Before adding any new medication, check it against your current ones. OmniRx's drug interaction guide walks through the process and offers a free interaction checker.

Which should you use? A 30-second decision

Frequently asked questions

Which is cheapest: SingleCare, GoodRx, or Cost Plus Drugs?

No single service is always cheapest. For same-day fills of common generics at a local pharmacy, GoodRx and SingleCare split the wins roughly evenly and the difference is usually under $1.50 per fill. For 90-day mail-order supplies of generics, Cost Plus Drugs is frequently the lowest because of its transparent cost-plus-15% model. The reliable approach is to check all three for your specific drug, quantity, and pharmacy.

Is Cost Plus Drugs cheaper than GoodRx and SingleCare?

Often, but not always. Cost Plus charges its acquisition cost plus a 15% markup, a $5 pharmacy fee per prescription, and shipping that varies by location. On cheap 30-day generics those per-order fees can make it more expensive than a GoodRx or SingleCare coupon at a local pharmacy. On 90-day supplies and moderately expensive generics, Cost Plus frequently wins because the fees are spread across a larger order.

Can I use SingleCare, GoodRx, and Cost Plus together?

You cannot apply two discount cards to one fill, but you can use all three strategically. Use Cost Plus for 90-day mail-order maintenance generics, and compare GoodRx and SingleCare coupons for same-day fills, controlled substances, brand drugs, and anything Cost Plus does not carry. All three are free to check.

Does Cost Plus Drugs carry controlled substances or brand-name drugs?

No. Cost Plus Drugs is generics-focused and does not dispense controlled substances such as Adderall or alprazolam. For controlled substances, brand-only drugs, and urgent same-day fills, use GoodRx or SingleCare at a local pharmacy instead.

Does SingleCare work at CVS when GoodRx does not?

SingleCare has maintained more consistent acceptance at CVS than GoodRx, whose CVS relationship has been unstable. If your pharmacy is CVS, SingleCare is generally the more reliable card. Always confirm acceptance at the counter, since terms can change.
