Why is it so hard to buy parts from people

Had a deal happen to me while in Florida this Winter.

Visiting Florida for the Winter and Minnesota is my home base, same with my cell phone Minnesota area code number.

Texted the guy 30 miles away in Florida said I would like to come by and purchase your item for sale. When is a good time and day.

His response, yeah sure come by. That was it.

If you didn't say, "I'm in FL on vacation right near you in (Insert city)." Then the assumption is scammer from the seller.

Should have laid it out better if you didn't. Communication... JMO

People don't think to ask or say, "sure when you coming down from Minn", which would have been my response. Cut the extra out being proactive.
