RaceTrac review: pricing/coupons

Was at store 10/14/2019 around 8:15 pm, I'm a rewards member and was using a $1.50 coupon which was only scanning $1.00 off. At the same time the guy next to me was buying to beverages that had price tags of $1.39 each in the cooler but were ringing up $3.50 for both. We both inquired about our discrepancies and were given attitude and no resolution, basically just deal with it. It may just be $.50 or $1.00 but it's MY $.50 or $1.00. Will not be back to this store!
