I guess it poses the question of... Does it really matter?
I'm saying this just to play devil's advocate. With that said, how many images from a subscription plan does the average buyers really download a month? 10, 20, 50, 100, 1000?
The answer to that really determines how much your images are being sold for (and what you are being paid for them). Also, if this deal is worse or just the same thing being sold in a different way.
