Isn't Bitpays fee 5% (?)
I've signed up for it just to see what it's like for a potential retailer in Australia and it charged $105 in BTC for a $100 QR code, are Zynga getting a special deal or sum shit?
Bitpay does not charge that much of a premium. Probably the merchant or retailer added 4.8% extra charges for processing BTC transactions.
