Not a PO but I got 18% off a white dial SMP300M diver back in October (just switched to it today funnily enough). Lots of chat about discounts drying up recently but one can but ask. I'd like to think 10% is still achievable. One thing that's certain is that the Omega Boutiques are almost certain to not entertain discounting so focus on the rest of the AD network. Good luck and I'd be interested to see how you get on.
