The actual cost is hard to calculate :
Most people don't 'stumble' upon Amazon : they go there for a reason. So they will wait until the site is back up.
People who did accidentally stumble upon Amazon ( just googling for a product ) , will see a site that doesn't work, and ignore it, so that might be a lost purchase.
However, I think the biggest cost might come from the knowledge that Amazon got hacked : even if hackers didn't get anywhere near the users' credit card information, most people won't understand that, and the idea alone will scare people away ( I'm sure the media coverage won't help either ).
Luckily, people quickly forget, so the losses will only be short term.
