I have had 4 sales (2 I assisted on) 1 was an accident and the 3rd was the right time at the right place kinda scenario. I have had many medium sized deals.
My top 2 sales would combine to be a 6-figure sale, but don't have an individual 6-figure sale. I've had cases where I've brokered domains and gotten 6-figure offers on them...ones that quite honestly the sellers should have taken, but oh well, to each their own!
