Search with Microsoft Live, get cash back. That's the new mantra behind Microsoft's Live Search Cash Back program, which has its own dedicated homepage and works like this: you search for a product using Live, buy the product through the search engine, and then save. The site explains "Every time you make a qualifying purchase, we'll send you an email to confirm your Live Search cashback savings. When your cashback account reaches a balance of at least $5, you can claim your cold, hard cash."
Here's a screenshot of the interface:
It's an interesting system, though it does show the great lengths Microsoft is taking to get a share of the search pie. Will it work? I think it could, as long as people are using the search engine regularly for this purpose and if they're finding what they're searching for.
