WARNING: If you're upgrading to version 3.2.2 or later, please make a note of the YAK add-on modules you have enabled. There will be errors after upgrading caused by a number of file renames (trying to figure the incorrect plugin name on the WordPress site site (ie. this page). You will need to re-activate these modules after upgrading. This will only be required once (i.e. it won't happen on the next upgrade).

YAK is an open source shopping cart plugin for WordPress. It associates products with weblog entries (in other words, posts), so the post ID also becomes the product code. It supports both pages and posts as products, handles different types of product through categorisation, and provides customisable purchase options -- cheque or deposit, basic credit card form, basic Google Checkout integration, standard PayPal integration, PayPal Payments Pro, and Authorize.net and MiGS (Mastercard Internet Gateway Service, add-on only).

Detailed installation and configuration instructions can be found by purchasing the YAK Handbook, but basic installation instructions can be found here. If you want to do something more advanced, post a message in the forums, or consider buying the Handbook.

The following add-ons are currently available:

• YAK Gallery - a gallery plugin for your products
• YAK AddInfo - configure additional fields on the final order confirmation
• YAK MiGS - a payment module supporting the Mastercard Internet Gateway Service (payment gateway)
• YAK Order Tracker - a module providing the facility for customers to view the status of their orders.
• YAK Membership - a members module for YAK. Sell membership through YAK, and then restrict access to parts of your site.
