I ordered this pack and paid the default $5 by mistake (with a bit of laziness), and would bet quite a few others had the same experience.

When ordering, you had to enter your amount before adding it to the cart, with $5 as the default. There wasn't an option to change it later that I could find. By the time I realized it couldn't be changed, I was through most of the ordering process and didn't feel like starting over.

It would be interesting to see how much better they would have done with either a more intuitive checkout (assuming I missed an option) or had more options in the process.

Developer for the site here. We definitely talked about this in the post mortem. Do you have any specific changes that you would have made to make the process more clear?

I don't remember having any trouble with actually ordering the pack.

I do remember trying to bump the payment to $10 and not being able to. Adding an option to change the amount paid during checkout or making it much more obvious if there was one may have helped your "haul".

Note that the humble bundle actually lets you increase your contribution "after" you've paid as well. They might be worth emulating there.

Separate shipping and billing addresses. My fiancee ordered a pack for $5, put in her credit card number, and put the address of the person she was buying it for in the shipping address slot. Then she realized there had been no place to put the billing address.

Long story short, the credit card charge went through, the package did not get shipped, and she's in the middle of resolving the situation via email with somebody at CaH, hoping her giftee gets their gift.
