Randomly display one or more Amazon products in the sidebar; products are selected from POST-specific pools, or from a 'default' pool that you define.
The Amazon Book Store (formerly 'Support Great Writers') Widget provides a very simple way to display up to two products in a sidebar widget on your blog, magazine, or other WordPress-powered website. The widget can be instantiated multiple times, with different products being displayed in each instance, enabling you to quickly add several products for sale to your site.
As of version 1.1.0, the you can define a 'pool' of products from which the widget will randomly pick up to two (per widget) for display. You can also define a unique pool of products for use with an individual POST, allowing you to quickly build up an Amazon Book Store of products that are related to your POSTs.
