My insurance company was giving me all sorts of problems in trying to refill an Rx a month early--I needed the meds since I was going out of the country for an extended period. The retail price at my local Walgreen's was over $450.00. I found the GoodRx site, printed the coupon, and the same Walgreen's filled the script for $46.00. GoodRx solved my problem and saved me over $400! Very impressed!
