Royal Oak 15450 Grey dial discount in UK AD?

[zen123]

I was calling a few dealers as to availability of a grey dial AP Royal Oak 15450 and on the third AD was told they have one coming in next week for display sale. Retail price is £18900 which I was advised there was no discount. I do have some purchase history with the AD having bought a Zenith from them earlier this year. So can any members advise if it is still possible to get discount on said watch? I read some forum posts from 2017 that people were getting 10-15% discounts so not sure about now.
