That is good to know; thanks! If I see them go up several dollars, I'll try to get one. Sounds very different from the one I used to do.
When you factor in prep time (downloading and reading the guidelines and survey) and drive time, you still must be at least around 45 minutes to an hour, I'd guess, depending on how far the location is. So I'm thinking $20 is about fair for that. Not like the other ones, where you have to do the "match" demo. That's a 10-ft pole job at anything less than $30, unless the place is 5 minutes away!

I've learned to never trust spell-check or my phone's auto-fill feature.
