I dont know any for non-members....but for members you have to have 2 computers or be able to multi log on the SAME world. Take both accounts to blue dragons in taverly duegon. One brings money, the other brings super energy pots with like 15 open spaces (and food and anti sheild). The account whom needs the money picks up the BLUE DRAGON SCALES which respawn quickly all over and close to each other. The account with money buys it, its 14k per 20 I beleive. I've transfered 300k per hour using this method. Hope this helps.
EDIT: Red spider eggs may work well in non members? Not sure. Or anything that respawns quickly and is 300gp+ think about it.
