QuckShop 1.2.4
QuickShop 1.2.4 by Isaac Rountree is a WP Shopping Cart plugin that works out of the box with WPMU 1.3.3, allowing blog admins to sell stuff from their blogs using paypal or other forms of processing. Usage could not be easier. The blog admin simply places one of the two supplied widgets in their sidebar and then enters a text string in their posts or pages which is converted into a shopping button on display.
Development for QuickShop has been centered on WP developments and the latest versions require WP v2.5, however version 1.2.4 (Direct Download Link http://downloads.wordpress.org/plugin/quick-shop.1.2.4.zip) is WPMU compatible and can be placed directly into the wp-contents/plugins/ directory. The plugin correctly reads the blog admin e-mail address assigned to the blog and builds it's shopping buttons correctly for each blog.
