Saving 3+% in credit card fees is good for buyers and sellers alike. There's always the option to pay 1-2% for voluntary escrow for eBay/Craigslist/etc, but for purchases from reputable companies (Amazon), it would be unnecessary. There are other advantages to crypto-coins, but that one alone is non-trivial. I don't expect that fiat currency is going away, but if the price and perception of BitCoins becomes stable enough (a big if), we'll see more and more trade, probably with BTC discounts to account for its deflationary nature.
