Love both shows.
As some have said already, anyone who is claiming that the AP guys are "preying on the elderly" have never had to deal with executing a large estate after a loved one passes. My grandparents had saved so much stuff (as a lot of people who lived through the Great Depression do) that we ended up just getting a dumpster and trashing 90% of it because it was just way too overwhelming..
For these folks to get some money, not too mention the satisfaction of actually cashing in on some of the items they have been holding onto for so long, is a service. It is not surprising that most of the old guys on the show always say they would love to have the American Pickers back at any time when they are interviewed at the end.
