OT: Anyone know the answer to this!

Three friends see this old TV advertised for £30, so they ask another friend to go and get it. They each give him £10. The friend goes to the store only to find the TV is now £25. So the shop gives him £5 change. He wonders what to do with the change and decides to give the friends £1 each back and he pockets the £2.
So the item cost the friends £9 each.
3 x 9 + 2 don’t make 30.....does it
Anyone heard this before because this fucker on holiday told it me over a few beers and 3 weeks later it’s still doing my head in
