We had our product feed set up and fetched yet products not appearing in G shopping (although linked to our adwords account). Products were showing "waiting for review".
I've sent an email to support and about 48 hours later someone from Google visited our ecom site, registered an account and made a test purchase going all the way to the payment form (stopping there). 10 minutes later we receive an email from g support telling us that all is OK and products should start showing in search soon.
From looking at our logs i can see that they actually checked the site to make sure it is a legit business. The guy actually looked at our mailing address and business info page before proceeding to register an account, put something in the cart and proceed to payment.
Hope that helps...
