Sony price-matches their approved sellers, and right now Borders is selling the 950 for $239.99.
The catch at Borders is that it's pre-order only, but you can get it now. Simply call up Sonystyle sales instead, and have them price-match it to the Borders price.
They will price-match it even though it's pre-order, but you may hit a snag if they try to tell you they can't price-match it because the 950 online page at Borders doesn't list a part number for some odd reason. Apparently, they "have" to see the part number to price-match to verify it's the exact same item.
However, in this event, simply ask nicely to speak to a supervisor if necessary. They will price-match it.
