Microsoft canceled their free Live Product Upload, for those of you who don't know what the service did, it was similar to the Google Shopping Engine. As an online merchant I had very high hopes for this program because of the runaway success of Google's Program. It is being replaced by the Cashback program which Microsoft launched last year in a partnership with Ebay and quickly spread to the rest of the web. It offers a percentage back to they buyer's Paypal account if and only when a sale is made.
