Horrible! Who sends people a code to use IN THE STORE saying they are approved and it's ready for use!? Only to be denied at the register! What?! And then to top it off after having customer service graciously try to figure out why it can't process for half an hour only to accidentally discover it can't be used for FOOD AT WALMART!?? THEN having to apologize for leaving a cart full of groceries only to go to the car and THEN get an email stating that they ACTUALLY CAN'T APPROVE IT...NOT OK!
