This is an interesting variation on selling overthe web. Instead of having a warehouse full of different things goingTODAY.com offers just one item each and every day (well, many different copies of the same item actually). They're usually biased towards the music geek and can be paid for with a PayPal account.
So instead of thinking about what you want and then going searching fo it, they've turned the whole concept on its head. You go there every day and see whether the apotheosis of musical geekness they have today is something they want.
It's a very interesting way of turniong a shopping site into a buzz destination.
Very much worth checking out.
