The thing with bitcoin is with the exception of a couple of very valid use cases - the big one being international money transfer (super-easy and super-cheap with bitcoin compared to other options) - most of the benefits of bitcoin payment processing are on the merchant side - cheaper processing, no chargebacks, no PCI etc.

Unfortunately, at least for now, bitcoin isn't a popular enough method of payment for the vast majority of merchants to worry about, let alone pass the savings they get from accepting bitcoin on to the consumers.
