Call the branch first and try to get a pricematch. Get the persons name whoever does the pricematch and confirm they have it in stock in the relevant branch, then let them know that you'll pick it up in person. It's important that you follow this procedure because they do try it on if you just turn up but don't have the name of the person you spoke to or the price you agreed upon. Sly ********!
I tried a few places today and couldn't get my hands on one as they were out of stock! Found a ebay seller who had 3 brand new with 1 years warranty 2 HD-DVD's & a HDMI lead for £431 all inclusive of delivery.
