First couponing experience was terrible

I just went shopping at walgreens and had everything planned out beforehand. So basically i did my shopping and a few coupons didnt apply which made my total $30 when it should’ve been like $14, so I called customer support and they said they would put the rest in my mywalgreens account but it isnt in there yet😭😭. I also stupidly pressed digital receipt for some reason, so now i cant use rebate apps. 🫠 edit: ok the credits are in my account now im still upset about the digital receipt thing tho😭
