There's a big difference between by being ripped off and paying retail. For instance If a newbie bought some posters from you're online store Dave, they would be paying retail prices, not necessarily paying too much. The tough part is buying posters that have never been auctioned or have never sold online before. When this happens I research what the US posters in that title have sold for in the past..
