Many thrift stores separate the accessories away from the machines; sell the machine for 24.99 and the accessories for 7.99 they can make more money that way. Also people steal the accessories all the time. Crazy. Anyway, did you do a walk through of the store to see if they were in another area? Also, check in the electronics area - in the tubs of cords -for your foot controller. They sometimes end up mixed in with the other junk because people in the back think they are game controller foot pedals.
