one thing im learning from the research im doing now is that coinstar do not pick up the coins and put it into their bank. instead the shop empties the machine and then puts it into the shops bank account. thus i think if i get a reply it would be something like the retailer has to offer a bitcoin exchange service to be able to offer it through their box. as the funds never really reach outerwall inc
That makes sense - there is really not much point in sending a truck around to pick up the change - the supermarket/Wal-Mart already has that happening - so yes some existing service would ideally be involved. In the US either Coinbase or Circle spring to mind. I suppose they might both have problems with AML/KYC type issues - and now that I think about it there's probably no viable way to get around those regulations in the United States. But again I doubt that anyone using CoinStar to get some fraction of a btc will be all that concerned about strict anonymity.
