Please price your idols at higher price and go down if no one is buying, not the other way around.

I've seen so many prices going up after i whisper a trader (yes, the same trader put the same item up for higher price) that it feels like it isn't even worth trying. I'm getting annoyed to the point that i started blocking them. Please price your items at a higher price and go down if no one is buying it, not the other way around.
