Widget Cart is a WordPress plugin that adds ecommerce to any WordPress website with widgets enabled. You can add a shopping cart to your new or current website as easily as adding any other blog widget. "Add to Cart" buttons can be inserted anywhere in any post or page; the cart sits among your other WordPress widgets where users can change the quantities on the items they order before checking out at PayPal.
It only needs a WordPress- based website, widgets enabled, and your PayPal account to receive and handle orders.
The project is in its final stages and needs testers. The plugin is more or less feature-complete according to my tasklist, which means upgrading it to a final release will (hopefully) not require any more effort by the testers than replacing the plugin files.
Widget Cart will be available for public download and submitted to the WordPress plugin directory when I'm satisfied that it works properly and has sufficent documentation. For now I want to be able to notify anybody affected by updates.
Widget Cart is GPL'd. I will never require registration or payment for downloads and documentation. It was heavily influenced by QuickShop, which is designed to serve slightly different purposes; if Widget Cart interests you but you're using a checkout system other than PayPal I encourage you to try it instead.
