I used GoodRx today on a prescription my insurance doesn't cover and got it for an absolute bargain. To echo a comment above, Rite Aid had the best price by $10. All I had to do was pull it up on my phone. The pharmacist even coached me on how playing with the number of tablets can bring the price down further. For example, a 90 day rx cost $15 while an 83 day rx cost $11.
