Quoted from ovfdfireman:

No reason really, Dealers taking a small deposit on the Special and Classic to know they are serious buyers. The only reason why someone may want to preorder is because they will be first in line to get them. To some people that matters, getting one fast. People that commit to a game will have one placed in their name right way, and it will never go to stock.
I get why people don't want to pay up front (that's a choice), I also understand why dealers do not want to "call it sold" without a small monetary commitment. I expect only a few classics and a few specials out of the gate, so if I tell people I am sold out and send them to buy elsewhere, I want to be sure they are in fact sold.
It is very common to put 5-10% if you want to reserve or hold an item,that seems fair. However, that is clearly the buyers option whether they would like to hold one or not.
I am cool either way!

Quoted from ovfdfireman:

I think the dealer agreement is irrelevant. Regardless, deposits for LEs have been collected since Transformers LE, Stern required deposits on Batman 66 LE. JJP required full payments on games. I have games in stock, those are paid in full. If you want to buy a game there needs to money involved.
Deposits are simply a financial guarantee that your word is good. I would like some sort of commitment from you as a buyer if I am ordering you an $8000 game, with your trim selection etc. Especially on limited run games. I think that is fair. Though I am willing to talk with customers individually and accommodate.
Chicago Gaming has already bought the parts and is soon starting production, I don't think they are looking for cash as much as commitment. Once a dealer pays, the games are theirs, it eliminates cancellations etc.
