There's a bit of a catch though: You'll have to download Wendy's mobile app and find a coupon for the deal in the offers section, according to a Wendy's spokesperson. But if you do that, you'll receive the free burger with a purchase. Wendy's didn't say if there's a minimum amount for the purchase, but it just so happens to be running another promotion that'll get you any size fries for $1 right now, so there's a chance that could be the way to get your free burger and make a meal out of it at the same time. The best part, though, is that this offer refreshes every day through the 23rd, so theoretically, you'll be able to get a new free, square-shaped burger every day.
And frankly, you can't can't afford not to.
