I'm not sure if this is a bug or if I'm missing something, but lately I've been trying to put bushels on the market for over $900 and I get an error message saying something like my goods were unable to be placed on the market. I'd have to lower my price a little before they go on the market. Is there some kind of price ceiling for market goods or something?

it's something to do with the private market price, you must be a theo or have lots of military tech? don't think you can sell for a certain amount over what your PM is, but someone should come along with a more exact answer.

you can't sell for more than 3x your private market purchase price
