Two sides to the problem
I know resellers are a problem, but honestly, they do it because they will always have people who are going to buy. I just hopped onto a Whatnot where someone selling some PALM pins, I asked for a couple of prices and was honestly astounded, mainly because the pins are still available on PALM's website! Then someone else asks them to run a pin that is currently available for $50 on the site for $75!!! I had to close out. The more I learn about pins and get more into collecting/trading the more I realize that Whatnot is definitely not it, at least for me. I recently started doing some trading in FB groups and let's see how that goes.
