I know I’ve missed quite a few pages of comments so won’t bring up old discussions around audit requirements etc, but what surprises me is people don’t mention the whole discounted gift cards or credits.
In Australia for a long time it was quite common to buy iTunes and App Store credit at 15-20% off. AFAIK if I used discounted gift cards/credit to buy something on the App Store, it didn’t impact how much the developer got and just came out of the apple margin. Granted since they integrated all apple credit into one balance those promotions are a lot less frequent but again, I don’t think the “3% payment processing cost” is really too accurate either since there’s plenty of people who use prepaid credit acquired at a discount. And even if we disregard this, let’s not forget not all credit cards cost the same in the four party model (ie how much each party charges in each transaction, and how it’s impacted by the “value” or type of customer and card status).
