Adrian,
I've encountered many dealers selling copies of ANH:R at Collectors Fairs, Memorabiliaat the NEC, Collectormania and even at one stall at a Car Boot at Birmingham Wholesale markey on a Sunday morning. There are a few that turn up on Ebay and iOffer.com. It's something that can be questioned, but then again - Ebay don't question it. Star Wars is a big revenue to them - look at the Holiday Special DVD's all over it.
