You may change the day and time of your order simply by calling your local store. Contact information for each store is available on the store select screen. Rosie will soon be releasing a new feature that lets directly modify your order, as well as change the day/time of pickup or delivery.
If a customer is not home for the delivery, or does not come into the store for pick up, the store and/or Rosie will attempt to contact them to schedule an alternative time within the next few days. If this is not possible, the customer may be charged a restocking fee to replace the items.
