True.  Everyone talks about how Bitcoin has no merchant fees, but they have to pay to convert BTC to fiat, pay for development costs or integration with a payment processor, and worry about the exchange rate.  With credit cards, fees and chargebacks are known and built into the cost of doing business.  With BTC, they're not as well known.

The advantage for Bitcoin is not retail sales.  It's person-to-person payments, long distance payments, micro or mass payments, and high risk businesses where credit card fraud is a big problem.
