|I am in New Mexico. Some ads have numbers and some don't.|
I have never bought anything without speaking to them on the phone first. If no number then their return email should have a number......if not.... no sale.
I also sell on Craigslist.....with no number but always reply via email with a number. You can tell a lot about a person listening to their voice and how they speak.
Wondering ??? which state, city or country you are viewing.
