If you previously purchased items from the selected vendor, you can view your purchase history and select items from it to add to your current order. For example, if you are ordering from JOY’S UNIQUE BOOK SUPPLIES, you can view your purchase history by selecting either the History button in the entry window or the Purchase History button located on the History slide-out menu. In the Purchase History window that appears, you can select any item(s) you want to add to the current order.
