Things happen fast here... Just got an email from PriceMe's tech folks who found this thread.

They tell me those retailers are in their database but since they aren't paying clients they usually don't show up in third party listings like ours.

As a special for Geekzone uses, they are going to start listing prices for those retailers in our pages. It will be a few weeks before this happens though as they have to put this change in the queue with other projects they have currently going.
