Method 1 and the Simplest Way - Switch Browsers

The easiest way to start a second order without finishing your first order is by switching to another browser or computer to place the second-order (Firefox, Explorer Edge, Chrome, Safari, etc). Each browser can only store one cart at a time, but you can use multiple browsers to store a different cart with each browser.  Just remember which browsers you were using.

Method 2 - Write Down Cart Id 

To start another cart without losing your current cart, write down your cart ID so you do not lose your shopping cart.  Your cart ID is located at the top of the box that contains your shopping cart (see image below).  Keep this cart ID handy so you can retrieve your cart when you are ready to continue shopping.

Enter the checkout and press “Cancel Order”. Once again do not forget to write down the Cart ID of the order you wish to continue later. Canceling an order deletes the Cart ID from your computer, but does not delete the cart from our system. If you wish to retrieve the other order, use the transfer cart link. This is found in the shopping cart box beside the Cart ID as shown above.
