A friend asked me to help build a website with a simple shopping cart. I looked at several carts but, for the volume, thought the Google Checkout approach would work best. When I found this plugin, which made it even easier, everything just came together. My friend now has a wonderful "online store" page and it was all put together in under a day, thanks in part to the simplicity of the plugin. I should add that Michael was quick to assist when the download link went to my friend (who was travelling) and not to me. He quickly sent it to me and I was up and running. Great plugin and great , personal support. Highly recommended.
