This has become a very popular service and feature that many Stampin' Up! demonstrators and other businesses have looked into to help supplement their income and to continue building their blog or online presence.
This service is currently available for Typepad and Blogger users. Click here to view pricing and details for each platform. Currently, Paypal is used for the online payment method. I am researching Cartville as well.
Please feel free to ask me if you have questions about any of these services.
