A client of mine needed her store to go online and without too much work getting the e-commerce portion of it up. I could have chosen from the myriads of options out there but I found WP-Shopping Cart, then their Gold module, and then they released Grid View.
I wrapped all those up in a custom wordpress theme and within a week I had everything up an ready to go.
Let me know what you guys think... I know I need to expand the width, as the site itself is a bit thin at the moment.
