They had this deal last Christmas and again this past summer. I always take advantage of it. What I do is purchase gift cards to my favorite stores like American Eagle (for my 14 year old), Children's Place and The Disney Store, among others. These are stores where I know I will be spending money. The gift cards can be used on anything.
One neat thing that happened last Christmas was I purchased a few items at Children's Place along with a gift card. I used a coupon for the items, but they took off the cost of the gift card too. I paid 20 percent less the my gift card amount. I will try it again this year, but that may not happen again.
We pay our credit cards in full, so that helps to save money too. And, the cash back is always nice.
