How many times have you been scammed by amazon or newegg or other major brand.
Never. I've had one or two people attempt to cheat me on e-bay, but have had no trouble getting my money back.
Also true cost of credit cards is more like 5%+ not 1%. If you could buy everything you currently buy on amazon (or insert favorite retailer here) for 5% less would you?
Not from a Bitcoin vendor, or at least one which did not have a long and stellar history. The ethics of a high percentage of the people in the community are appalling to me, but this is not surprising when one thinks about it a little bit given the nature of the strengths of the solution.
I'll start to think about patronizing Bitcoin merchants when they start to think about sending my the item first then I pay when I receive it.
I would suspect that it will be a fairly long time before BTC is good for run-of-the-mill mail-order crap (absent an undesirable scenario where it is highly regulated.) BTC strikes me as being pretty good for either paying periodically for services (e.g., a shell account) or for face-to-face transactions. And not much more.
