tacosDo you eat at Jack in the Box on a regular basis? Know someone who does? Then you’ll want to take advantage of this special. From now until Nov. 30, when you buy a $20 Jack Ca$h Card, you’ll get another $20 card free. If you’re looking for a Christmas present for a fast-food lover or two, this might be an easy gift idea.

The only catch? You have to use an American Express card to pay for the cash card, and you have to buy it over the phone – it’s not available in the restaurants. If you want to take advantage, call (800) 955-5225, then press Option 3 and then Option 2.
