i thought exactly the same thing...
but Saracen told me otherwise, with a megapost.
search for 'scan xfx problems' (it's the scan offer £25 pound one..) it starts when i say ' why are you all bashing SCAN, i thought it was the manufacturers problem after a year...'
the retailer can only recommend that you deal with the manufacturer, but if you are insistant, then you can do it through the etailer using your legal rights (tis often faster to do it through manufacturer... but when they are in a different country... it makes a bit of a postage hike...)
you do get the odd company like SCAN who deal with everything through themselves though... but i'm not sure what ebuyer are like in that regard.. plus the fact that alot of people think the 1 year thing is in place... you might just get bounced back and forth.....
