Does Cost Plus Drugs accept insurance?

No. They’re cash-pay only. This means payment doesn’t count toward your insurance deductible or out-of-pocket max — but the cash price is often cheaper than your insurance-negotiated price.

Can I use my HSA at Cost Plus Drugs?

Yes. Prescription drugs are HSA-eligible expenses. Pay at Cost Plus with your HSA card or reimburse yourself from your HSA.

How long does Cost Plus shipping take?

5-7 business days typically. They only ship, no walk-in pickup. Order refills at least 10 days before running out.

What drugs does Cost Plus not carry?

Specialty biologics (Humira, Keytruda, Enbrel, etc.) are mostly not available. Controlled substances (opioids, ADHD stimulants) are not available. Cold-chain drugs requiring refrigeration are limited.

Cost Plus Drugs vs. traditional pharmacies — when does transparent pricing win?

Mark Cuban’s Cost Plus Drug Company (CostPlusDrugs.com), launched in 2022, prices drugs at a formula: manufacturer cost + 15% markup + $5 dispensing fee. No insurance accepted, no PBM negotiation, no hidden rebates. Radical transparency in an industry built on opacity.

The question every patient should ask: is Cost Plus cheaper than my insurance? The answer depends on three variables: your insurance’s copay on the drug, whether you’ve hit your deductible, and whether Cost Plus stocks your drug.

When Cost Plus wins

High-deductible plans. If you have a $3,000 deductible and your drug’s retail price is $400/month, paying Cost Plus prices pre-deductible is often cheaper than paying insurance-negotiated price pre-deductible.
Uninsured or cash-pay patients. Obvious win — no other option comes close.
Generic drugs with big retail markups. Imatinib (generic Gleevec) retails at ~$10,000/month at big pharmacies. Cost Plus: ~$50/month. Massive win.
Drugs your insurance doesn’t cover. Cost Plus bypasses formulary entirely.

When insurance + copay card wins

Brand-name drugs with active copay cards. Copay card + insurance often produces a $0-$10 out-of-pocket, which beats Cost Plus’s pricing even on heavily discounted generics.
Drugs not on Cost Plus’s formulary. Cost Plus stocks ~1,000 drugs. If yours isn’t there, insurance is your option.
Medicare Part D users with low specialty-tier coinsurance. After 2026’s $2,000 out-of-pocket cap, Medicare Part D becomes competitive for specialty drugs again.

Head-to-head examples

We compared 5 common drugs as of April 2026. Prices are 30-day supply.

Drug	Retail pharmacy price	Cost Plus price	Typical insurance copay
Imatinib 400mg (generic Gleevec)	$9,800	$47	$80 (Tier 5 specialty)
Lipitor 20mg generic	$25	$12	$5 (Tier 1)
Lisinopril 10mg	$18	$8	$3 (Tier 1)
Sildenafil 100mg (generic Viagra)	$175	$35	not covered on most plans
Metformin 500mg ER	$22	$11	$5 (Tier 1)

Pattern: Cost Plus dominates on expensive generics (imatinib, sildenafil) where retail markups are enormous. Insurance with copay card often beats it on cheap generics or common brand drugs. The right answer depends on the specific drug.

How to check your drug at Cost Plus

On every drug page on RxCopays, we deep-link the Cost Plus search by generic name. One click shows Cost Plus’s price if they carry it.

The catch

Cost Plus doesn’t accept insurance, so whatever you pay doesn’t count toward your insurance deductible or out-of-pocket maximum. If you’re trying to hit your deductible, pay through insurance.
Shipping only. No walk-in option. 5-7 business days from order to delivery.
Formulary is limited. ~1,000 drugs as of 2026. Specialty biologics (Humira, etc.) are mostly not available.

The bigger picture

Cost Plus is a transparency movement as much as a pharmacy. They publish their acquisition costs publicly — every drug’s “manufacturer cost” is visible on the product page. That alone has pressured PBMs and retail pharmacies to justify their own markups. For patients, the right move is using Cost Plus when it wins and insurance when it wins — and checking both, every time.
