My dad sold these on the side when he was in the air force - 30 years ago! It was a great vacuum, but I think we got ours cheap. They are HEAVY!

Idea #1: Watch the demo and say, thanks...it looks great...I'll go buy me a refurbished one for 1/3 the cost!

Idea #2: If you are really not interested, you may want to cancel...the poor salesman probably has his hopes up.
