It is just a program! The Pickers make an offer, the seller either takes it or not. I would love to see some of the objects they buy either restored and sold to someone who will share it with us to enjoy (once again), or, sell it to someone who really enjoys seeing it as they remember from their youth.
These guys are just businessmen who happen to enjoy their jobs. Most of the stuff they buy have very little commercial value, and, much of the stuff they buy they have to put money into to make it presentable to the public for either viewing or sale. The asking price they show on the screen is just that, an asking price, how many times do they actually get what they want for it? In case you haven't noticed, they have not beaten any elderly people up to force them to sell. Either enjoy watching the show, or, watch something else!
