Maybe it was just a coincidence, but not an hour after I bought Tales from Monkey Island, Chase closed our Amazon Visa account and issued a new card due to 'suspected fraudulent charges.' Prior to that my wife received notification of an international charge.
All of the transactions check out, we didn't see any other charges that were unknown to us.
Oh well, my Amazon card was wearing out anyway...and I got Monkey Island for a great price.
Don't worry about missing a deal, almost all of them repeat. I missed one I wanted and about 3-4 hours later it was up again. Not a big fan of this type of sale, it's a big waste of time.
They're also giving out free games in limited quantities, but it's basically impossible to get them.
