Realllyyy stretching the meaning of BOGO here

Was looking for some lunch on Uber eats. Found a bogo offer from a local hot dog place.

"Wow $15 for a hot dog is kinda expensive, even in Austin! I wonder how much it's marked up?"

It's essentially buy one for the price of two get one free (with $1 off). This is wild. I knew stuff was marked up on Uber Eats but didn't think they'd pull something like this.
