I see filter style Grabow pipes go on eBay for $40 with shipping. It amazes me. They are a lot cheaper at the drug store. I would buy every Grabow on the market if I knew I could double the price.
It is like people who buy all the tickets for a sports/music event and then sell them for a higher price except the pipe will always be available so just boycot the seller untill he is forced to lower the price
