I was underneath the Virgin Megastore on Oxford St. yesterday and the 'Play' store is advertising a special sale thing.
Obviously, no small print was to hand but it would appear that most/all the guitars are available to buy now but you won't have to pay anything until 2007.
Assuming you won't be forced to pay on the HP at that point and can slap your lump sum on their counter, that's a whole year for you to save up the Â£580-odd quid to own a proper Fender Jaguar, or the Â£1000 to own a Ricky, etc.
There may be other things covered like keyboards 'n' shit.
Off ends the end of Feb apparently.
