store cards have a long inactive period, usually 1+ years, especially jewelry stores are good about it cause it's not every day most people buy jewelry. Again you can just buy a gift card online and use the gift card to pay off your kays account.ope one of the easiest things to get, but don't get something you won't ever use imo. If your going to use it then fine, otherwise you can buy kays gift cards online and use the kays gift cards to make payments at a store lol.
