I purchased an Ultimate Teens gift card last September during the 15% sale and I have literally made like two successful transactions using it.
I have contacted Ultimate gift card several times and only ever get stupid responses like "Unfortunately, this is not a participating retailer in our Ultimate Gift Card program" when they clearly are.
I am at a loss for what to do as most of the balance is still active and I am sick of trying to buy things and the card failing.
Which shop do you try to use your cards? You have to make sure you have enough money on the card to cover the transaction. (i.e. if you have $2 left on your card, you can tell the cashier to charge you $2 on your GC and the rest on your other forms of payment.)
