Comet's new site launches tomorrow at 10AM (GMT). According to the email that has just been sent out, the product feed will be updated at the same time to reflect the new deep links - so make sure you update!
(Comet is my highest earning merchant on the Price Tapestry demo site so I hope it all works! :o)
Users: DGM Pro (used to be UK Affiliates) have announced the same thing.
David: Out of interest, how many users do you get on your demo site per month?
