These questions are not about on the game itself, but about the community and players of the game. Additionally, they sound like shopping advise.
Prices and value when trading with other players are highly subjective, and will vary from one person to the next. Even jargon is not always universal across a game and will vary from player to player (though terminology questions are allowed per the FAQ). At what point, if ever, can a question not be about a game (or hardware) and be about a player or community instead?
I assume a question like: "Is $10k a good price for an english copy of Kizuna Encounter?", is not welcome as shopping advise. Therefore a question asking, "Is 63 buds a good price on Max's Severed Head?", shouldn't be either.
I'm not 100% sure how to approach these, as I flagged one and answered another.
Edit: Another example of a community question about trading game items, though this one was deemed off topic.
Here's another community based question.
