Unfortunately, this is what I sometimes experience, and I am not sure there's much that can be done. I am already trying to filter out outliers, but if a price looks "plausible", this filtering doesn't do much.
Sometimes I get prices for items that are unavailable or completely off (perhaps from a 3rd-party seller?).
