It seems a few days too early for an April fool?
I particularly love the idea that "restrictions apply"
* I'm seeing it here for example - 29 Mar 2007, 13:35
** UPDATE: 29 Mar 2007, 17:15 - Gone a few hours later ... Anyone care to comment on whether this an April Fool that got loose a couple of days early. I'm tempted to try the checkout code just see what happens - and to see if it checks for a spend in excess of £100,000.00
