You can only add additional items to your order if the store shopper has not started preparing it (Order is in "submitted" stage). If the order is under preparation by store, you may call to add items. It is up to the store to accept your request.
1. To add an item Go to Orders -> Choose the current order -> You will see a + button on the order screen. You can add items by clicking the + button.
Reasons for not being able to add an item:
1. Your credit card is authorized for a lower amount in the initial order so we are unable to add new items to the same order. In this case, please create a new order.
2. The shopper has already started procuring the order. In this case since the shopper has either started shopping for the order or looking at the order, to avoid confusion we do not allow to add new items. Please create a new order and send us the both order # at firstname.lastname@example.org and we can in some cases waive the delivery fee on the new order.
