Shop Owner Discount?

[M16]

I have a connection that owns jewelry and watch shops.

I'm looking at Audemar Piguets, Rolexs and Breitlings.

I know I can get some sort of discount from this connection, but I don't want to even bring it up if it won't be a deep enough discount to make the watches affordable.

Anybody have any idea what type of discount I could expect if I was getting it at cost or something close to it? Or what would a reasonable discount be to expect?

Thanks
