Let me tell you some of the things that have gone wrong over the years. 1) Checker waiting for you because it takes so long to purchase a card. 2) Purchasing gift card fails for no reason. Too bad, no points for you. 3) Being sold an invalid gift card! Embarrassing when the restaurant has to 1st figure out how to take a digital gift card, then comes back and tells you it's invalid. I had to pay with another card. United refused to refund my gift card. I had to perform a charge back with Chase!!
