I think the best you can do on the iPod Touch (not iTouch) is to look for one of the sales where they give you a gift card (Target and Circuit City comes to mind) with a purchase of iPod Touch...Usually price matches are for brick and mortar stores and not online stores.
A ten second search on Google showed this:
jr.com has it for $289 plus free shipping.
