Poor purchasing etiquette

[fencer]

I think if a person responds to your ad and low balls the price you have to choices
1. Not to respond
2. Counteroffer
The reason why people low ball is because of the term obo put in ads

BUT

If you strike a deal and they try to low ball you at the door. They get an invitation to walk right back out. I have no further interest in every selling anything to that party again. Sadly there are some Canreefers who do this.
