Paul,
I take your point about having already given them the price, but it doesn't necessarily mean that the customers were lying when they said they wouldn't pay £220+ vat.
I'd rather charge a moderate price, do an excellent job for more people and reap the benefits of all the repeat and referral work that will surely come my way because I charge a fair price for a fantastic job.
Don't get me wrong, if people are happy to pay over £220 for something that is only actually worth half that then fair dinkum!
Paul,
Top coats and redying or one thing, but we're talking about just cleaning and conditioning. I don't do that, neither do most so there's a good market for your training courses.
