Google Checkout Blues

I recently ordered a Wacom tablet for my girlfriend's son's birthday off of Google Checkout. The seller was "The Deal Specialist". Google Checkout processed my credit card and sent the request to the seller. The problem is, the seller never got back to me. I tried sending the seller two emails but they never responded. I checked out the Google Checkout Forums, and found a link to a customer support response page. I filled out the information, and Google replied within hours saying that they will try and contact the seller. Google Checkout policy says that if a seller does not respond, Google Checkout will refund the money back to the buyer. The email stated that either the seller or Google will contact me within 5 business days. I have mixed feelings about this experience. I am disappointed that I will probably not get the product for my girlfriend's son's birthday, although I am happy that Google responded personally saying that they will contact the seller and get back to me. I am unsure at this time whether or not I will use Google Checkout in the future. What are your experiences with Google Checkout? Have you ever been ripped off by an online purchase?
