I have got a used BPP practice and revision kit unit 1 and 2 9th edition as well as the official manuel guide. Those cost well over £200 and I'm selling it at £180. The condition is excellent as I've taken good care of it. No pencil marks and it's nearly like brand new. If you're interested, PM me!!! 
If anyone has edition 10 please let me know!! [email protected]
