Just by giving a starting value predisposes people towards that value. And in this case, it was low enough people would impulse buy with the default value left in. Contrast to the Humble Bundles where their true value is much larger, so people tend to weigh the value against other purchases from their peers or prior purchases (which is why the median prices seem invariant between bundles).
