Get a Free Sourdough Star at Carl's Jr.!

Carl's Jr. is offering a free Sourdough Star to My Rewards members who upload proof they've driven past a Jack in the Box. Valid proofs include photos, screenshots, or GPS routes, with reports confirming Google Maps screenshots are accepted. To redeem, simply upload your proof via the app, and if approved, you'll receive a free charbroiled Sourdough Star.

While this deal isn't a significant price drop on a product, it offers a complimentary item in exchange for proof of passing a competitor, which can be especially appealing to fans of the Sourdough Star or those collecting rewards. The simplicity of proof upload makes redemption straightforward, and the offer fosters engagement between the two brands.

Considering the unique nature of the deal—getting a free item just for proof rather than a discount—this is a creative marketing promotion. We see value in the novelty and potential for frequent redemption, but the overall savings are limited to a single free item rather than a substantial discount on a purchase.
