Two years ago, I got halfway through sorting a similar kind of bargain bin. Not with food items in a supermarket but phone cases in a convenience store (already unwrapped so not labeled with phone models, so my main guide was camera count and position). I surrounded myself with piles on the floor, camera count on one axis, camera size on another, before I made enough clear space at the bottom of the bin to start piling them up - the most common ones as foundation to prop up a bookshelf-like variety display of about 3-5 each, neatly stacked on top. I then used insertion sort to add to the sorted stack from the assortment. Then I struggled to find floor space for the rare leftover ones so that I could put the rest of the overrepresented ones at the bottom and finish the browsable display. I did all this with my unprotected phone in the other hand pretending to compare it to whatever I was holding but I guess it became too obvious with the uniquely-shaped ones. The cashier walked over and made me throw the rest back as quickly as possible.

Speaking of ADHD, I specifically asked my psychiatrist to get tested and it came out negative somehow. I think I could really use the meds but the doctor won’t let me. :(
