There are going to be times (a few days or weeks) where sellers think they can "outlast" the competition in a price war.

You're basically betting that the other guy doesn't have the stamina to survive at this price.

Of course, if what the OP says is true, if the other seller has a much lower price point than you do, you can't outlast them. They could still be making a profit at $20 while you're losing $5 per unit trying to push them out.
