Walgreens review: refund policy

My husband went into to our local Walgreens to purchase 2 Visa gift cards to give our grandchildren for their birthday. He picked up 2 gift cards and went to the register and placed $50.00 on each card. As the cashier was finalizing his purchase, my husband wanted to confirm that the cards could be used anywhere. The cashier tells him NO, that these gift cards are for Walgreens ONLY. Well, our 6 year old grandchildren don't have much need for Walgreens gift cards, so he asked if he could cancel those cards and have the $100 he JUST SPENT placed on Visa gift cards (which is what he thought he was purchasing) and the cashier tells him NO. So, he spends ANOTHER HUNDRED DOLLARS to get the Visa cards. Yes, I realize that he made a mistake by accidentally picking up the wrong cards, but it is RIDICULOUS that he could not cancel gift cards that he just paid for and have his $100 applied to the cards he came in to purchase. Walgreens may have profited by his mistake today, but once we use up these Walgreens cards he accidentally purchased, I promise that Walgreens will NEVER receive another cent from us. I hope refusing to help him out with his mistake today was worth it to you Walgreens! My husband is a business man himself and thank goodness does not treat his own customers this way.
