Their parents?

Once upon a time the only thing I wanted for my birthday was 4 tf2 keys at $2.50 a piece.

It's not unreasonable.

$10 doesn't seem unreasonable. The highly-charged verbiage of "preying on kids" made it sound like they were bleeding them dry.

Parents have the ability to control their children's purchases. If they don't, well, that's on them.
