If you already have a PriceGrabber account, you do not need to sign up for a new account. If you do not have a PriceGrabber account, you must sign up for a new merchant account with PriceGrabber since Yahoo! Shopping listings will now be powered by PriceGrabber.
Effective March 11, 2010, you’ll no longer need to submit a feed to Yahoo! Product Submit. The listings you currently submit to PriceGrabber will also appear on Yahoo! Shopping, starting March 11, 2010.
