Sign Up for Google's Trusted Store!!
Google has made it clear that being a member of their 'Trusted Store' program will be important to ranking and results during and after this transition to the new PPC Google Shopping. The Trusted Store program was limited to invitation only but we have learned that this program will open to the public on Tuesday, June 5, 2012.
Due to the high demand anticipated for this program, it is advised that you sign up early.http://www.google.com/trustedstores/become-a-trusted-store.html
