Only took the one.
Shaun, like Pete said, no secret really, just ask for it.
I brought a sample with me of carpet I clean which was around £100 a yard.
It is these types of carpets that you can charge £1 a foot for.
At the start of the show Pete was nervous of charging 50p, by the end soon realised 50p isnt enough.
Best, Dave.
P. S. I might add the envirodry machine ruined my sample so I cant post a picture of it. Len and Jason both saw it though, so ask them their thoughts and if £1 is enough?
