I won't use them. I go to the cashier line. WalMart started using them but now they are back to cashier's as people were having more problems with the self checkout. Plus, they have to pay someone to help people using the self checkout anyway. What does bother me is people who get in the express lane and don't use cash. Standing there waiting for the 3 people in front of me to each pay with their debit card and have to reenter their pin, then ask for cash back, then sign the receipt is not express!
