Two reasons. If you can’t find it you might find and buy something else. The same reason all the seasonal (Christmas, school supplies, Halloween ) stuff is in the back of the store. Also we did this with Target all the time. Called it resetting an aisle. Moving everything ensures that anything that was hidden behind something or misplaced is put back in its right place (zoning). It’s basically a super zone. A reset aisle looks very neat.
