When you order using the same email address, all your previous purchases, whether in-store or online, are stored under the Orders section of your Ace & Tate account.
To re-order an exact order, log in to your account and go to My Account > Orders. If the order is available for re-ordering, you’ll see a "re-order" button next to the invoice. Re-ordering is only possible if the item is still in stock.
Please note that this option is not available in the UK.
