// nope it is set so high in order to keep to economy in some sort of balance... most of the items I find on corpses i leave, simply because they have no real marked value, bronze weapons are an example of an item that has no marked value, compared to a iron weapon the bronze version is utterly useless...
If you have a item that you have no use for and can't find a buyer for, the only way out is to throw it in a trash can or sell it to the pawn shop however with the prices the pawn shop offer it is of no consequense what you choose.
