I get my TP and paper towels with my amazon subscribe and save. It keeps me out of Wal Mart (AKA hell). I agree that buying in bulk isn't worth it for smaller households in the long run unless you have really good storage space.
Costco has some really good things; but for one person, the membership fee is not worth it. Buying in bulk does not usually work for one person or a couple. If you have a basement or a huge store room, perhaps.
I have a membership for BJ's. I have had it for years. I used to get some things for my dad from there, stock up on paper towels, TP, and other stuff. I am thinking about not renewing the membership this year. I can pick things up at my local
Rite-Aid with sales and coupons. I also have cash back rewards from them, so it works out better.
