Where is the API to check out and complete a sales transaction? There really isn't a point to the project is a user cannot check out.
In the Product Details documentation (http://developer.sears.com/?q=content/documentation), it reads:
"This section details how to find out the correct catentryid using the product details service. this catentryid can then be used as parameter for other services such as add2cart."
I do not see any documentation about the add2card function? Is this an upcoming planned function?
The developers should also check out Tesco's API (the largest grocer in the UK) at http://www.techfortesco.com/forum/index.php?board=13.0
Their API allows you to check out, enable users to store shopping list favorites, and schedule deliveries.
But this API is a good start!
