A website I currently maintain switched domains from pamelahirthstudios.com to pamelahirth.com. Along with the domain change I integrated the website with wordpress in order to use the Shopp plugin to make it easier for the client to maintain the store. It’s been a useful plugin so far with a good support community, worth the $55 . However, I was disappointed to find out that pages of the store did not keep accurate breadcrumbs like I desired, so there may be some hacking around to do. The other paid option for wordpress commerce is the WP eCommerce plugin, which has a free option but does not support multiple product images. I went with Shopp because the support seemed better. Anywho, give it a look.
