Is it really a retail key or MSDN retail keys??? i believe most of the keys online are just msdn, bizspark keys....as the original ones are not sold separately...

Your price looks very expensive, so just wanted to know why is it so expensive... msdn office 2013 are sold at very cheap price in my opinion(may be 10-20% of your price)...check the other threads here....you'll know about the price...
