I've had probably 100 people to my house to buy things via CL. I ALWAYS keep my item in the garage and keep the garage door open. My husband is in the house if I need anything. I've had lots of flakes-people that make an appt. to show up and don't, and one nasty experience with a person who bought something and then demanded to return it after getting it home. The problem with selling electrical items is that you need to show that it works to get your asking price. So, that's why I sell sewing machines from my garage. I'd never sell them or get my asking price if I met them somewhere. I occasionally get folks who want to dicker, but if I"m firm in price, I put that on my CL ad and that's that.
I will continue to sell on CL and have met some very nice people and have even made a friend...
