The sandwich features a slight variation on the chain's signature Sourdough Jack and includes ranch sauce, a Jumbo beef patty (the same one you find on a Jumbo Jack), shredded lettuce, tomato, bacon, and American cheese on toasted sourdough bread.
It's paired with a small order of fries and a Coke Freestyle fountain drink for $4.99 (may vary). It's basically Jack in the Box's answer to the current influx of 5 for $4 and 4 for $4 deals by some of the other major burger chains.
You can find the deal at participating locations through the end of May.
