Dave Gold, the owner of a liquor store, paid extra attention to an effect already well known to retailers: “Whenever I’d put a 99 cents sign on anything, it was gone in no time. I realized it was a magic number. I thought, wouldn’t it be fun to have a store where everything was good quality and everything was 99 cents?” Gold went on to create the 99¢ Only Stores chain, which now numbers 332 stores.
