Why Metformin Coupons Don't Work as Well as You Think
Three structural problems with the coupon model — and why bidding fixes all of them:
1. They expire or change without notice
Coupon prices for Metformin can change daily as PBMs renegotiate rebates. The "$X coupon" you see on Tuesday might be gone Thursday — and the price at the register often differs from what was advertised.
2. GoodRx and SingleCare sell your prescription data to PBMs
When you use a discount coupon, your prescription history, dosage, demographic info, and refill cadence are shared with the PBMs that profit from prescription data. The 2023 FTC settlement against GoodRx confirmed this practice in detail.
3. Limited to select pharmacies — yours may not be included
Coupon programs only work at participating pharmacies — usually big chains. Your local independent (often the cheapest cash-pay option for Metformin) may not accept the coupon at all.

Frequently Asked Questions
Are Metformin coupons still worth using in 2026?+
Less than you'd think. Coupon programs like GoodRx and SingleCare have published prices that look like discounts, but they're typically 40% off retail at best for Metformin. Script Unlock's verified pharmacy bids regularly come in lower (~$2/mo) because pharmacies actively compete instead of accepting a fixed coupon rate.
Why is the price on a Metformin GoodRx coupon different from what I pay?+
Coupon prices change without notice — sometimes daily. The advertised Metformin price may not match what the pharmacy charges at the register because GoodRx renegotiates with PBMs constantly. Script Unlock bids are locked once accepted, so the price you see is the price you pay.
Does GoodRx sell my Metformin prescription data?+
Yes. GoodRx, SingleCare, and most coupon companies share or sell prescription, demographic, and behavioural data to pharmacy benefit managers (PBMs), advertisers, and data brokers. This was confirmed in the 2023 FTC enforcement action against GoodRx. Script Unlock does not sell or share your prescription data.
Can I use a manufacturer coupon for Metformin?+
Manufacturer coupons exist for some brand-name drugs but rarely for generics. They also typically exclude patients with government insurance (Medicare/Medicaid) and have annual savings caps. For Metformin, a Script Unlock cash-pay bid almost always beats both manufacturer and third-party coupons.
What's the real cheapest way to buy Metformin?+
Cash-pay through a competitive bidding marketplace. Upload your prescription to Script Unlock and verified US pharmacies bid against each other — current low bids for Metformin start at $2/month. No coupons to clip, no expiration dates, no PBM middleman.
