Change an Order

To change an order, find it on the Your Orders page and click the order number to make changes. Once an order has gone into shipping it can no longer be changed.

Add an item to an order

Use the box at the bottom of the item list marked Add an item by ISBN, UPC or product code: type the code, choose how many and press Add to Order. If the item is already there, use Change instead. Orders paid by credit card can't be changed.

Change quantities or remove items

Click Change next to the quantity, type the new number and press Save. Setting it to 0 removes the item. If some of that item has already shipped, the line says how many: set the quantity to that number to keep what's on its way and drop the rest. Orders paid by credit card can't be changed.

Cancel an order

Cancel this order is at the bottom of the page, and asks you to confirm first. To cancel part of an order, change that line's quantity instead.

Attach a tax exempt document

An order showing tax has a Tax Exemption box: attach the tax exempt document and press Upload, and we'll take the tax off before it ships. See Tax Exemption for more info.

Pay by card

Orders under $800 can be paid by credit card. Click Add Credit Card Information.
