Macau AD experience

[Lennxi]

Hi guys, I'm heading to Taiwan Hong Kong and Macau in December and wonder have you guys ever shopped in ads in Macau? And what are the chances to pick up a stainless steel sport models such as gmt or sub or even daytona.
I know all these grey market bs in hong Kong or other asian regions so not giving any hope or wasting time going to ads there. But I over hear people talking about their lucks picking up stainless steel models in Macau.
So what are your experiences and please share it with me.
BTW, I have a hulk and batman both bought at ads in north America without waitlist nor some bs vip customer privilege. Super lucky:)
