He does that on PL as well but, honestly, I never took offense. I just undercut again. If he's able to sell that many items, it means he's working his butt of to get them in the first place. Not trying to sound offensive here, but maybe you could do the same. I don't see how lowering the market price is a bad thing, it just means more items will be affordable for more people. And, as said, probably the prices right now are just ridiculous.
