I'm curious what licit, low volume, etc. products actually would make sense to sell in Bitcoin vs. something else.
The best thing I can come up with is online-delivered services from non-US (and ideally, non-developed financial system) countries, to other non-developed-financial-system countries. Like, a guy in Zimbabwe who wants to provide an online service to someone from PNG. Which is really a stretch to imagine.
The advantage to using Bitcoin is that there are no payment processing fees. What we're able to cut with BitcoinStore is that 1-10% fee that Visa, PayPal, et al. charge especially when dealing with products that have a high chargeback risks. So the products that sell best when using Bitcoin have high chargeback risks associated with them.
Assuming bitcoinstore hasn't ripped off their previous N customers, I'm fairly confident being purchaser N+1, especially if my transaction isn't "special" in any way.
They would have a lot to lose by ripping off customers, vs. a random seller on silkroad, so I'd feel comfortable up to a few thousand dollars.
I think I've actually bought something from Memorydealers before. I'm not sure of the relationship between bitcoinstore and Memorydealers. If they're the same entity, then I'd be fine up to $100k or so -- it's a real business.
For the 1-3% fee businesses, it does actually make sense. Especially with really low-margin sites. Think of your local grocery store offering a cash discount because of credit card fees, those businesses really do exist on the margin.
