Hi everyone, long time reader of the site, first time poster.
The actualy price of this this item at Best Buy isn't really a deal, £350 is the going rate and is widely available else where (Richer Sounds etc).
However, having just ordering this afternoon - Quidco is tracking at £52.50, which potentially makes this sub £300 - pretty good deal is the cash back comes off. Free delivery as well.
I think the Quidco/Best Buy 15% ends tomorrow, so you'll have to be quick.
