The blog is a great tool to let your customer know about upcoming promotions, new products, sales and more. This is my second blog post. 

This is your blog. You can use it to write about new product launches, experiences, tips or other news you want your customers to read about.

We automatically create an Atom Feed for all your blog posts.
This allows your customers to subscribe to new articles using one of many feed readers (e.g. Google Reader, News Gator, Bloglines).
