If you are diligent on ebay and look only for pin lots, you can get traders for $2.50 max including shipping. I have bid on over 50 auctions and won five with the winning bids ranging from $1.70-$2.50 per pin - all real parks pins - (always factor in the shipping costs to your pin bid since they can vary greatly) and don't bid over your set limit - another pin lot auction is coming right along! Then you have all different traders and don't feel like you are always trying to unload the same pin everyday.
