Reading the forums on their site it was a much bigger problem and not isolated to them. For the record I've shopped there quite a bit and never had any problem - although admittedly not for a while as their prices aren't as competitive as they once were.
But that price for the PS3 changes that! Very seriously tempted by that. Found Killzone 2 online for £15 in the Platinum range due out that Friday too... sooooo... close to clicking order.
They still don't ship the PS3 with an HDMI cable though it seems - which is very stange. They sell the console as ths 'true HD experience', make a big deal about 1080p and BluRay and then don't even ship with HDMI

Still, cheap HDMI cable is only a fiver so no biggie, but does just add to the weirdness!
