Discount when purchasing 2 watches & an engagement ring

[Wizzle47]

Hi guys, been lurking around here for a while whilst trying to figure out my next watch purchase to mark a recent achievement. I'd narrowed my choice down to either a speedy pro or a date just ii and then managed to justify buying both of them together.The Rolex can be a reward for my achievement and the omega can be bought with the insurance money I got following the theft of several watches during a break in at my home. I lost 5+ watches, buying 2 back is only fair!

I'm also planning on purchasing my Gf of 5 years an engagement ring. The ring she likes luckily happens to be from a jewellers that is a Rolex & Omega AD. I thought I could use this opportunity to see if I could get a decent discount when purchasing all 3 items together. If they don't offer me anything significant I'll buy the ring and source the watches elsewhere.

What type of discount would you push for if buying 3 items together from an AD?
