I always take cash to the vendor booths and use my credit card at Hancocks. Some vendors still use paper forms, so who knows where you credit card number lays until they get back to their store. Most of my cash is in my shoe between the insole and the shoe until I need it. I just take my shoe off in the privacy of a bathroom stall and pull it out as I need it. The shoe "system" and a fanny pack, along with a cloth, zippered shoulder bag let me shop till I drop.
