I looked up price bashing (using Google, haha) and didn't get satisfactory results. Can you provide a link that gives a good explanation?
Price bashing is when a competitor lowers prices to the point where they are losing money on the transaction. The desired effect is to destroy the competition and once the competition is eliminated, to raise prices to an artificially high level as a monopolist.
EDIT: Found it - http://en.wikipedia.org/wiki/Predatory_pricing
Well that explains why you have such an average grasp of the concept.
