> > 11+ at $999.99 each > Wow... Prices should better be sub-additive, since otherwise market arbitrage opportunities appear (in this case: to get more than 10: buy 10, and find some friends who also buy 10). If such an irrational pricing appears, it is a sign of market failure; in this case: if the demand is higher than the demand, prices have to increase until for the given pricing level supply=demand. This is how markets self-calibrate.
