If you opened the package and there was a random serial number included for the bonus content that was linked to that package's specific serial number, and it was anyone's guess as to what bonus game it unlocked...then the choice of bonus item would not be yours.
Your inability to purchase from the location offering your choice of bonus item, or just simply your unwillingness to find a way to do so (e.g. ask your parents to order it for you from said establishment), is your choice to NOT choose the pre-order bonus you desire.
I simply don't understand the logic (or lack thereof) behind this thread.
