its not anyone's fault - some retailers order X amount, and then sell them all as "pre-orders". Other retailers order X amount and don't put them as pre-orders.
Then the manufacturer and distributer ship things places.
So you could be #10 on store 1's pre-order list and be waiting while people are walking into store 2 and buying off the rack.
It's not a joke, it's the risk you took. The pre-orders are a stores decision, not distributer and not manufacturer.
