Your replies pretty much align with my research as well. About 6 months ago, I dropped my prices from $24.99 to $14.99, expecting a spike in sales. Looking over my paychecks from before the price change, my revenue is currently less than half what it was before.
It would appear to me, that a paysite purchase is indeed an impulse buy where price takes little consideration. A higher price may even make a site a more attractive purchase.
