Seems like a possible price mis-match between shop.com and firebox.
Firebox are the merchant and on their site the price is £99.95 (http://www.firebox.com/?dir=firebox&action=product&pid=1441), however if you buy through shop.com they have it at £77.95.
shop.com seem to have a price promise - "We Guarantee that the prices on SHOP.COM are the same as those found directly on the shop's site."
Has anyone had any exprience with shop.com? Worth a punt?
