Retail employees, can you explain how preorders get messed up?

Here's some added info for people wanting to automatically roast Nintendo.

This specifically regards the MM3DS, but it goes to show you it's not all Nintendo fault.

To preface, I must also state that Nintendo is NOT a toy manufacture by design. They are a software company and dabble in toys to promote their software and business. They were upfront about the Amiibo situation long ago--that they only intended to print so and so quantity of certain characters and would only restock the main ones they believe would be a safe to produce. It's not some crime they under estimated the items would be so hot AND that many people buy multiple items to play, collect, AND mod (and scalp).

Anyways, back to the point. Many on here seem to think Nintendo failed to deliver the stock they promised just because some preorders had not been met. What you don't realize is that most of these orders are made through PHYSICAL WRITTEN CONTRACTS WITH SEVERE PENALTIES FOR FAILING TO MEET SAID TERMS.

For the mm3ds, many retailers had contracts on the number of items they were to get. In this instance, GAMESTOP screwed up when they did their preorders and over sold what they were contracted with Nintendo to get. Nintendo only produced a SET LIMITED quantity and held GAMESTOP to the amount they originally were contracted to receive. GAMESTOP then pulled out their lawyers to find a loophole in the contract with Nintendo and demanded an additional allotment to the original quantity. Using this tactic, they forced Nintendo to re distribute the quantities the other retailers had order. This is part of the cause of BESTBUY's huge cancellation of many preorders (GAMESTOP had pretty much stolen a good portion of BestBuy and other retailers' allotments.)

This was the mm3ds fiasco, but it go to show you it's not always the main suppliers' fault on these issues. Many times, it's the fault of greedy retailers overselling.
