I expect Steam games to go on sale often and don't buy until they drop below my $25 threshold. Since their sales (revenues) are increasing, that means I'm not as cheap as I thought... However, the problem with playing with your pricing is the same reason why airlines don't massively discount unfilled seats. Since the fuel is already paid for, why not discount those seats and make money? It's because people will expect the price to always be discounted near the end, ultimately leading to lower revenue.
