Ange should do a quick price check when you drop an item and suggest a range of prices.

You can set any price, obviously. But there should be a slider within reasonable price range for you to pick a price if you're clueless.

It should be clear to a player (from dialogue with Ange) that her suggestion isn't 100% guarantee, but a somewhat educated guess. And GUI should reflect that pulling slider to the left (to lower price) would mean faster and more sure sell, while pulling right would mean that item might not sell at all.

Setting price outside of suggested range should prompt a warning, to prevent especially bad losses. But you should be able to disable that warning and (separately) the whole price suggestion if you know what you're doing.

Yes, I know about third party tools for pricechecks and whatnot. But new-ish people are copmpletely lost and have no idea how to price their stuff. Which leads to selling goodies for pennies. Or overpricing stuff, making it unsellable for days. And then they feel like they can't make any money in this game.

Sure it will put some extra strain on servers, but for a good cause.

Here’s a crazy idea, never b4 seen in history for selling things without knowing which price is the best.
