If you registered for the promotion at the Shop-Rite courtesy counter (not on-line) prior to Janaury 19, 2003, the computer may have erased your OP number and you may need to re-register. The easiest way to find out is to look at the bottom of your register receipt, if there is no indication how much has been spent toward OP miles, you need to re-register. However, registrations are retroactive to all purchases made from January 19th onward.
