had an experience like this when amazon had a bug in their system.
You could buy a board game, get another for free.
With that one you got for free, you could ... get another one free
... and so on
and then you could remove the origional game.
My friend received so many games that the dean of housing (at the college) had to talk to him because it took 4 golf carts to truck the stuff into the post office. He then returned them, minus receipt to toys r us (who sold them through amazon to him) and bought a playstation, some games, and a farkload of other stuff.
So yes, they have to honor it, but amazon fixed their bug within 4 hours of them placing their order....
