I've been selling postcards on ebay for over 26 years. I have a hoard of approximately 1.4 million postcards in stock. I also sell on WhatNot.com as well as in antique malls and live postcard shows. In my 26 years of selling postcards, I have handled and sorted through millions and millions of cards. I'll be posting what sold and sourcing videos, and other educational videos about postcards and the enormous amount of profit they can provide.
