The site itself is not necessarily a great showcase in terms of the wiki syntax or modules. However it does contain a working shopping cart and there are not too many wikidot sites with that.
Some notes here.
1. This is a Google shopping cart.
2. The default method for creating a cart was difficult to use with wikidot, in fact the default snippet of code provided for by Google simply did not work. The only way I could get it to work was to create an html page with the snippet then plug it into the site as an iframe which needless to say is annoying.
3. The method I used is part of a Google Labs experiment in shopping carts and it worked very well. Basically, you use Google Docs as a shopping cart data source that is scraped by Google Merchant services. A snippet of code placed into the site using the standard [[html]] renders the cart and the code works perfectly.
Obviously there could be some issues with more robust needs but all things considered, this worked well as a simple cart solution used on wikidot.
