I suppose (depending on the rules of the forum) we could start a merchant's guild that could help the issue by having the guild regulate prices in exchange for the shops being advertised heavily.
ie; you sign up for the guild along with ten other shops, every guild member has a link to the guild masterpost over in re-tail which in turn has links to each shop. Each shop uses at least the guild approved pricing, such as 20k or under for a hybrid.
I could go into more details about how it might work, but that's assuming something like this would even fly.
edit: I also do mean guild in the true sense of the word, not the one commonly used for mmos. A guild in that its a group of merchants coming together for a common purpose, rather then a clan of some kind. I'm sure there is a better word for it, maybe corporation? Union?
