[Yokuutsu]

Well, a preorder bonus should be awarded to those who ordered first. And it's not that hard to count preorders in the system and then get that many bonuses shipped to the store.

Now, if it was a physical thing you get WHEN you preorder....that's a different story. They get those in a certain amount, sometimes they may run out and that's acceptable...other times, they still have it when the game comes out (-looks at Pokemon X/Y preorder poster-)

And if they run out of the preorder bonus (Note: this one came in the case with the game so running out is them being dicks and not ordering enough) they should be willing to refund all your money for the item.
