Quick couple of questions to those who break up their workshop hours and have sales-only hours/days. 

How does that work for you? How do your users / volunteers feel about it?

What are you selling? Any "wow, we're surprised at how well Widget X sells!" items you'd recommend?

Do you get a lot of people coming in hoping to fix "just this one thing?" during the sales-only time? This is a main concern of mine.

Thanks,

Clifford
