Newb Question - Negotiate with AD????

[mfer]

First off, great forum. Just found it today and been reading quite a bit.

Well, I've been saving for some time to get a SS Sub No-Date (I was thinking that I only needed $3800, but now $4525 ). Oh well, I'm still gonna get it. I like the clean look of the crystal over the SS Sub W/Date. I wish they had a Sub that had the same date as the Sea-Dweller, but without the thickness, but I digress.

Anyway, I read a couple of threads today that people mentioned that they would negotiate with the AD on the price. I have only talked to two (one in St. Louis and one in Maui) and both of them said the price is set by Rolex and cannot be negotiated. Is it just the places I went. Can I negotiate? If so, what can I expect to get for a SS Sub No-Date. I will be taking a few trips this year to Maryland and Las Vegas. Should I wait to go there?
