Why sit there and keep on bumping up a dead post with nothing but everyone complaining about an obvious pricing error. It was a known crap shoot in the beginning, the OP knew this by the title. But everyone feels they deserve something for nothing because they tried to take advantage of a mistake. How would you feel if thousands of people tried to take advantage of you over a mistake you made? I am sure there were tens of thousands of orders to process and cancel, guess Amazon did not move fast enough with the cancelations.
This doesn't really qualify under the Amazon.com A-to-z Guarantee since no payment was received. If credit cards were charged that would be different. Price mistakes happen all the time on Amazon and they don't guarantee them. I do find it frustrating that some received their orders and some didn't but Avon is not responsible to fulfill all these orders. On another deal site this deal got 59,559 views. There is no way they could send out that many orders!
