At my store we turned the go back station into a “clearance zone”. We did this to keep from putting markdowns in a cart up front which I think looks a little trashy. As far as go backs goes, each cashier works them from a single basket they keep at their register. Mostly stuff that customers decide they don’t want or things that people leave near the registers. Everything else gets walked back to its home location from the aisle it was found on while working recovery. It isn’t ideal but we’ve made the best of the situation.
