They attempt to avoid refund laws as well. Apple claim you can't get a refund on the App store. Although they have to provide one if an App you purchase does not do what was advertised. (This was brought up on The Chasers show "The Checkout")
I accidentally purchased a $5 app not too long ago (it was in the group of apps that were free for the 5th anniversary of the App Store). I selected the "Didn't mean to purchase this item" option in iTunes and got a refund immediately. No problem.
