Came across this one on another website: A coupon for $1 off a grilled sandwich at Jack in the Box. These are the sandwiches that they were handing out free with the purchase of a large drink a couple of months ago. You can choose from Turkey, Bacon and Cheddar or the Deli Trio varieties. It’s not valid in Austin, Beaumont/Port Arthur, Lake Charles, Waco and a few other localities, but appears to work at all DFW-area locations. Valid through April 11.
