I believe he paid just over the minimum as to when the jeweller has to notify HMRC , I think its any amount above 10k euros.Back on the cash discussion. A friend has just collected a previously booked Rolex from a local jeweller. He paid £10,000 cash deposit about 18 months ago and the balance of £10,000 on collection. He's known to the jewellers as a long standing customer but they had no issue at all taking the cash as I was with him when he picked it up. I am now on the waiting list for a much less expensive version but doing the same thing. Cash deposit and cash balance when its ready to collect.
