I bought a round for 2x it's value.
Worked out at a total of £1,200.
The deal was I did the work & paid it back over 3 months. £400 per month.
If any customers dropped out I took money off the total. I think 2 in total dropped out.
Rounds where I live in the north of scotland sell for 2x or 3x its value.
South of the border they may sell for a lot more, but i'm not too sure.
Hope this sheds some light on the matter?
