Ive bought a couple of rounds, lost 1 or 2 customers, and that was because we increased prices after a few months as they were far too low. I paid 3 times round value.
Havent worked out the figures, but be good to know why he is selling up, if its all legitimate. And working the round once would be good, i did it for free labour (knocked it off the amount to be paid) so you get to see its all good.
When we converted our round of 6 years to wfp we lost another 6......drop in ocean really!
dont rush into anything, go into it with your eyes open. And if you dont know the guy, then be careful! sadly there is a lot of scammers around.
