Mine did not involve pricing.
I was to check shelves ro make sure they were at least 50% full of any given item, and that weren't too many empty spaces.
The majority of my audit was on ADA stuff. I took over 30 photos and couldn't upload them all, had to email the rest. I had to take photos of the lighting, handicapped parking spaces, any aisles which were blocked by anything, making them less than 3 ft wide, entrance to the handicapped stall, inside the handicapped stall, handicapped dressing room, and any handicapped accessible counters which were blocked or had stuff on them.
