I really think (or at least hope) no one seriously expected to get a €400 lens for less than €90. I for one was buying full well knowing that an error was much more likely than this insane discount. But who knows what happened, so why not take a free gamble if you could do with 14mm FF anyway?
well... i buy on amazon for years.
i once got a 230 euro gfx card for 80 euro.
another time i got a asus sonar DX card and one day later i got another one.
of course i payed only for one.
never heard anything from amazon.
sometimes you can be lucky.
i did not thought it was an discount..i thought it was an error.
but there was a chance that i get it for 88 euro.
i guess the main problem was.. to many have ordered.
and they did not send out the same day.
when they send you the email that they have send the product, you have a valid contract and they can´t cancel.
