MyWhitewalls is an online art gallery that puts up modern art and abstract art canvas oil paintings for sale online.
Hand-painted art pieces can be quite expensive to buy. However at this site, you can choose from a wide range of paintings to suit every mood and decor, at attractive prices. With added benefit of free shipping (check out the promo code on the home page), the total cost is quite affordable.
This site is built with Volusion, a popular shopping cart system and extensively exploits the SEO features of the cart to get good search engine rankings. The owner also uses Twitter to engage the prospects through the social media circuit. I noticed that they make good use of Squidoo and other WEb 2.0 properties to get their name in front of the prospective buyers. A good case study for an online only shopping site. You can find their blog here.
