Want to order DJ for wife, AD wants full desposit?

[Americany13]

So I wanted to order a PM DJ for my wife and I called up the AD, I was asked to come in .
I drove there and was asked for a full deposit, since they will order it for me . I'll be getting 20% off.
No time line or promises on when it would be coming. But they told me they have to get it from Switzerland.
It's not a hard to find model , I actually found it in two different ADs at full retail.

Do they just wait until rolex sends one? Luck on the draw?
Or is there an order with my name on it put in for me?
Thank you
