What is a reasonable discount off of MSRP?

[Saxon007]

Greetings from a newbie, I have a beginner's question.

I have always worn inexpensive Seiko watches but I am ready to buy something nice. I can't afford a Submariner so I am going to purchase an Omega Seamaster 300 M shortly after Christmas. There are 2 Omega ADs in my city of 1 million peeps and, oddly enough, they are located about 100 feet from each other.

I visited them today and both mentioned the same MSRP of $3400. At the first store (Tourneau) the salesman said they did not put items on sale but he would "work with me on the price". Since I wasn't buying it today I didn't ask for the exact amount of the discount. I visited the 2nd store (Bailey Banks & Biddle) and as soon as they found out that I'd already been to the Tourneau across the walkway they immediately offered me a 20% discount on the same watch -actually, on any watch they had in the store - good for today only. I feel like I've been car shopping.

Anywho, what can I expect as a reasonable discount on a new Omega? And, if you are familiar with them, is there a big difference in service between the 2 retailers? There are 2 more ADs in a city an hour north of me so I can shop around if I need to do so.

Thanks for any responses, this is a very informative place for a novice such as myself. I enjoy lurking around here. :)
