Pawn stars do stage there big purchase's, My mom went to the "pawn shop" while in Vegas, She said the store itself is tiny !
American pickers is half and half, They came to a freind of mine's property. The show when they visited "an old Studabaker dealership" in Lewistown, PA owned by Max Corkin.
He e-mailed them for two years about coming and one day a show producer and 2 "scouts" showed up and they pre- selected the items for purchase but did not agree on prices. 6mo later the whole crew showed up and for 2 hours they filmed there approach and departure and the interveiws than they did the walk through and filmed it as it went but only picked up the pre-arrainged items, and negotiated the pricing as they went, although Max told producers what he would "like to get" prior to filming.
