In todays world of reliable shipping companies
there is little need to know where a person is. I sell and ship stuff across town and across the country in the same way. maybe I don't want you coming to my house! Maybe its cheaper to ship across town than to drive. Maybe I just don't like people in general!
. With all the wackos in the world today one can not ever be too cautious. It is an old way of thinking that you need to know where someone is. And with the speed of web searches how hard is it to look up and address or zip code? If you are already LOOKING at an ad for something online, how tough is it to do a little search. IMHO...
