But it's true I also regularly hear reports of requests (even very explicit) to "bundle," especially from certain markets. My best suggestion has always been very simple: if a certain piece isn't available, either wait or run! ;-)
To the extent it's possible, *never* buy above MSRP -- meaning neither from a grey dealer, nor from an AD by including in the "deal" watches or jewelry you wouldn't otherwise have bought. I understand this might not always be easy to follow, especially if someone desperately wants a given watch but has no relationship with that brand and/or its ADs...but in the long run, I believe it is it the best way to enjoy this fantastic hobby!
Cheers.
