This time of year many businesses are offering bonuses when you buy their gift card. For instance AMC Theatres is offering a $10 concession card when you purchase a $50 gift card. Since I easily spent over $50 there last year and will do so again next year this is a good deal for me. If you know you are going to be spending money at a business anyway you might as well take advantage of these bonus offers. It is an easy way to save a little money.
This thread at Slick Deals has a list of bonus gift card deals.
