Yes I know what you mean. I only wanted to do it as I was responding to an e-mail enquiry (no telephone number), and instead of just whacking the price in, I wanted to try and show a little value for money, so I typed up a FAQ quickly. Then I thought perhaps it should be on the site anyway, in the off chance it might convince a couple more people to call.
I'll trial it and see how many views etc it gets.
