Bic Camera in Japan at one point used it as their "point" system. Unfortunately you had to have one of their wallets, but essentially if you bought stuff with them and you had registered for the bitcoin rewards, they would give you some bitcoins. You could also transfer your own bitcoins into the wallet. You could then buy stuff at the store with it at some nominal rate. I thought about buying a computer with bitcoins because when you could still mine with CPUs, I heated my apartment mining bitcoins (then I lost interest ;-) ). Honestly, this is exactly the kind of thing I was hoping bitcoin would turn into. When Japan outlawed crypto currencies, the Bic Camera thing disappeared (or it's possible it disappeared earlier... I wasn't paying much attention).
