My coupons stacked just fine but the whole experience was horrific. The cashier was awful, rolling her eyes and sighing loudly every time she had to scan a coupon. I was already nervous and the way she was acting made it so much worse I ended up paying $6 more OOP than I had planned because I panicked and used the wrong RRs. I think maybe next time I'll try using a different Walgreens. The one I went to was definitely not coupon friendly!
