Quoted from Bartzenegger:I would pay 50.00 bucks to add to or change to my Xmen pin. Songs and shots to music pins I'm still so shocked that this money maker hasnt happened yet
You've answered your own question -> $50 isn't really a money maker.
It would take more than $50 per willing possible customer to make redoing code a worthwhile "money maker".
For example, it's much easier to make pin-blades (stickers) than redo game code.
