Customers at Piggly Wiggly entered the store through a turnstile and walked through four aisles to view the 605 items sold in packages and organized into departments.

In November 1922, Saunders attempted a squeeze on the substantial short interest in the stock, running the share price up from 40 to 120 and profiting by millions on paper.
