The WP e-Commerce plugin comes bundled with numerous widgets that can help you further customize your shop and advertise your products.
They include:
Latest Products
Price Range
Product Donations
Product Tags
Product Categories
Product Specials
Shopping Cart
Depending on your theme, you may have multiple sidebars or other locations in which to place widgets. To view all of your available widgets and possible locations, navigate to Widgets under Appearance in your WordPress menu, as seen below.
Just like with any other widgets for WordPress, you can drag and drop one or more widgets anywhere that your theme will allow. Each of them offers a dynamically changing element that serves a specific purpose.
