Not sure if any of you guys have BJ's wholesale near you except Ant.
If you download their mobile app and use the self checkout line you can stack coupons prior to going or via the app while you are in the store. Their coupons always overlap by a few days and if you shop on those overlap days after you have electronically "clipped" both coupons for each month for that single item you get both discounts.
I told my sister cause she shops there and she's like "yea I know - Ive been doing that for years". I thanked her for telling me then she busted my balls for being a rookie adult
that said it's somewhat rare that items span both monthly coupon releases but sometimes they do and it adds up especially if you are crazy like me and only go every so often. This run was my frozen food run I meant to make a month or so ago.
also they were completely out of TP and paper towels. Freaking hoarder morons...
