yeah, i wouldn't know that either, but some places that deal in food items, do discount things for the employee's.
i had a buddy working for the local (then) Sunbeam bakery. he would get trays of whatever bread, rolls, muffins, that were extra's produced that day, or sometimes the stores could not take them due to overstocking...and sell them for company price for cash.
i see an Entenmann's guy twice a week at the local CVS, i can buy discounted Entenmann's from him.
