Back in October they ran this bundle for $9.99 as the deal of the week. It was supposed to last a week, but they ran out of keys several times. They restocked acouple of times, but they finally had to cancel the deal on Monday of that week after the publisher got skittish over how many bundles they were selling for so cheap.
Not gonna say that it will happen here. But it has happened before.
EDIT: Looks like while I was busy hunting down the link for the Square pack, jatan11t already posted about it.
Im sure Tony will be careful this time. Coz he knows the sales stats.
Amazon should add a tab in there web page called Game bundles or something. so people can look @ them easily. Amazon need to fix there Digital download page user friendly. Its not very impressive for my eye
