Buying Tag Heuer in France

Hi,

I have been on the fence to get a Monaco for years and now have decided to finaly do it.

I live in France and I was wondering if I could expect any type of price rebate for Black Friday in any of the general resellers?

(I understood from the Tag Heuer shop that they would not do anything on their side)

Also, I was exploring the chrono24 route and was wondering about it. Is it a safe purchase if I use their verification service.

Thanks.
