Here's a question: we all know about reducing the price point to garner more sales, and therefore more profit; has anyone done similar studies on what price point elicits the least number of refunds (especially due to buyer's remorse)? $8 seems "low" to me, but only for some items; I suspect that most eBooks wouldn't meet this criteria (although I have payed an order of magnitude more for eBooks and still have a minimal Safari subscription). An eBook at $0.99 I wouldn't see the point in getting a refund, no matter how easy it would be to get it. If it was a really bad book, I might go after the refund just to make a point, however.
