hamleys the gentleman's toy shop

For anyone who doesn't know the store - this is probably the best toy shop in the world , situated in Central London. For those that do , read on
Hamleys issues discount codes for staff, corporate and a few other things.Someone got hold of 3 of these codes , each entitling to 20% discount on purchases.
These guys then input all 3 codes to receive 60% off their [xmas?] goodies. Fair dos.
so said Hamleys which agreed that it would honour those sales. [ they stated that it was a gaff in the coding]
Lovely, in the Chrismas spirit and cerainly with the famous stiff upper lip and all that :)
Shortly thereafter , it then announced that the sales would not be honoured as it contravened the ters and conditions of those sales.
Hmmm, so initially it agreed to be a gentleman, then found out it didn't have to as it was no longer legally binding, so cancelled.
The age of chivalry in retail is now officially dead ....
