Exchange Super Widget
The Exchange Super Widget handles the Buy Now, Add to Cart, Cart Summary, Registration, Log in and Confirmation views depending on the situation. By default, the Super Widget allows the user to buy the one item immediately and shows beneath the product. After the click the Buy Now button, they are given the option to change their quantity or to complete their purchase.
If you go to your widgets in your WordPress dashboard (Appearance > Widgets), you'll find the Exchange Super Widget.
You can drag and drop that into any of your available widget areas. There are no options associated with the Super Widget at this time, so you will not need to make any changes.
