We purchase postage stamps in bulk from the Post office and sell them in books of 20. The expense is assigned to a "virtual inventory" general ledger (GL) code rather than to our merchandise for resale GL because this is a service item. (Same for movie tickets!) We post them into the point of sale inventory in a specific department and use the current UPSO SKU as the item number. We do not charge extra for them. This is a benefit/service to loyal customers (employees) and a way to get folks into the shop. We scan the SKU on the 20-stamp books at the register. We reconcile our sales to the GL expense to be sure we account in audit-fashion for every stamp sold. Susan Hester - WakeMed in North Carolina
