Beware! There are some vendors listing on Price Watch who may gouge you on the shipping costs after luring you in with a low price.
The prices are entered by the dealers directly and may not reflect any prices posted to their own websites. The dealer should honor the Price Watch price, but as P/W is essentially just an advertising service there may not be a lot of help for you there.
(If the price isn't honored, E-mail them at badprice@pricewatch.com, and if the shipping is unreasonable, E-mail them at shipping@pricewatch.com.)
That being said, there are some truly great deals here. Forget buy.com, this is the goods.
