Google Base used to be in 2.1, but is no longer in either 2.1 or 2.2. This feature has tremendous business value, and it will make nopCommerce a much more attractive e-commerce platform. Can you please add this to version 2.2? Thanks!
Google Base (Google Merchant Center or previously Froogle) was refactored (changeset c54c1a3795f3). The new version will be available in the next release.
