The 25% deal sounds like blatant BS to me. It says you sign up for Microsoft live then use the sponsored link to buy stuff of eBay and pay with Paypal. 60 Days later Microsoft will send you a check for the 25%.
All I see is a way for someone to now have your eBay password and your Paypal password. C'mon now, like Microsoft is gonna send out millions of dollars to people just for signing up for Microsoft live and buying stuff from anyone on eBay?
