I like my reusable bags. I check myself out from the store, and fill the bags myself. Gets me out a lot quicker, especially from the store that lets me ring up my purchases as I'm going through the store. I just set my reusable bags up in my shopping cart, scan the items I buy, and put them in the bags as I go. When I get to the checkout stand, I scan the hand held unit, and it shows everything I bought. Then I run my credit card, and roll on out of the store.
Easy Greasy!
