Humble Bundle Error?

Email them. Their support is pretty good :)

I mean 7.45

Did you pay the average value at the time or more than the average? You need to pay $0.01 MORE than the average value to get the Beat the Average (BTA) games. For example, if the average price was $4.75, you need to pay $4.76 to get BTA bundle. There should be a warning banner on the site saying you won't get the BTA games if you're paying less. Did you see that banner?

you obviously didn't pay more than the average. check "Like what we're doing? Click here to increase your order amount!" to see how much you're short from the average and add how much you need.

If you did not manage to beat the average at the time of purchase, you can increase the amount that you paid with a few cents in order to beat it. Hurry before price increases even more ;)

Yes, I payed more than 7.45. It didn't say the warning banner either.

Problem fixed, the Humble Bundle support saw that there was an error. Well thanks from the help from most of you.
