How do I change the quantity of a specific item in my shopping cart?

First, click the "Shopping Cart" icon in the top-right corner of your computer screen. This allows you to view all the items in your cart, as well as the quantities you have selected for each one. To change the quantity of an item in your cart, move your cursor to the "Quantity" field for that item and type in the desired amount. Once you have done this, the quantity and the corresponding dollar amount (if applicable) will update automatically, displaying the correct figures for both the quantity and the cost on the right side of your screen.
