You may be aware of the Vouchercodes web site, which lists codes you can use to get a discount on various web sites. The site does apparently qualify conditions associated with use of the vouchers (to avoid the kind of debacle that happened at Hamleys last December).
While I was browsing Amazon today I noticed this promotion which made me do a double take. This could be a simple mistake, but given that Amazon’s site is known to be highly dynamic I’m guessing that it’s their default position when there aren’t any real promotions available. I just thought it was interesting that they didn’t simply remove the text.
(Update: It’s gone now, so I guess it was a mistake.)
