Consumer investigator, chris chmura has a reminder not all cards in your stockings are created equally. Merry christmas. Our team heard from 43 people about gift card concerns. I want to talk about the bonuses stores are dishing out right now. They are actually pretty good. Theres an important restriction. Some stores are going to say, buy 100 gift card, get a 20 bonus. Here is the thing, you get two cards with two sets of rules. The 100 gift card cannot expire. The law prohibits them from expiring. The 20 bonus card is a different story, it might expire, legally. This is not a gift card. They are often called promotional cards, so, stores can apply expiration dates to them. Fair warning, many of the bonus cards we are seeing right now are only good for a few weeks into the new year. If you are enticed into buying the gift card for the bonus, read the fine print so you dont let the extra money expire. If you have a problem with a gift card, call us, 888996tips or www. Nbcbayarea.
