What is a cart?
Items you select to purchase online are placed into your shopping cart. You can have a single cart with your current order or multiple carts, each containing separate orders. Carts also can be saved for later.
The last cart you accessed is always the default cart. Selected items are automatically placed into the default cart. If you don't have any carts to add items to, a cart is automatically created for you with the default name Cart.
To manage carts, access the carts list by clicking My Account, My Activity, then Shopping Carts in the left-hand navigation bar.
