Search for an eBay item, get $250 back from Microsoft's shareholdersWonder why Microsoft is losing so much money online? Its Live Cashback offer isn't the sole reason, but it's symptomatic of the problem. Since June, Microsoft has included eBay in a program which offers users of its Windows Live search engine discounts when they click on ads and buy a product. Coupon-tracking blogs report that Microsoft and eBay have increased the discount to 30 percent, up to a maximum of $250. It's inconceivable that this can pay off for Microsoft, but there's no reason not to get a cheap laptop. Trust us, Bill Gates can afford it.
