Jack in the Box offers free grilled sandwich with any large drink

Mark your calendars.

San Diego-based fast food company Jack in the Box is offering a free grilled sandwich with any large drink you buy. The offer is valid only on Feb.23 and is meant to drive trial of the two new sandwiches added to the menu this month.

The turkey, bacon and cheddar sandwich features roasted turkey, two slices of cheddar cheese, and two bacon strips topped with a sun-dried tomato sauce; while the deli trio features Genoa salami, sliced ham, roasted turkey, two slices of provolone cheese, and two pickle fillets topped with a creamy Italian sauce. The sandwiches are priced at $3.99 each, plus tax.
