I needed a prescription refilled and wanted 3 months worth so I wouldn’t have to go back to the pharmacy any sooner. I checked goodrx for the cheapest pharmacy and had my script sent there. I printed my goodrx coupon for a 3 month supply. Picked up my prescription and found out my particular generic (matching the coupon) wasn’t in stock. They had a matching formula alternative available. They ran the coupon anyway and it still worked, seamlessly transferring over to the other generic med. The price was $2 higher than the one I thought I was getting, but the coupon still worked (amazing I didn’t have to reprint for the new name), matching the price on the goodrx website (for that new drug) perfectly to the penny. It was slick as a whistle. The pharmacist didn’t blink an eye. No problem, and saved over $50 on that 3 month refill. Didn’t need to fuss with an insurance deductible or high co-pay. Goodrx to the rescue!
