At first goodrx was helpful In finding decent prices.
It allowed me to make an educated decision as to which would be the best pharmacy for a particular med. Lately it seems the price is always higher than the coupon even though the PIN number matches. Upon contacting customer service... after getting through that awful automated system... I was told the price is always an estimate and may be off. I guess the best thing to do is call around (fun! More automation!) to make sure prices match.
All of our coupons are based on contracted rates at pharmacies and are used thousands of times every day without issue. If you're having a problem, we'd love to help - please email help@goodrx.com. Thanks.
