"Totally legitimate" copies of MS Office
My favourite on Amazon is the obviously fake copies of MS Office that are available. Aside from the unrealistically low prices, the fact that in many cases they're selling Professional Plus edition is a bit of a tip off. Pro Plus isn't available as a retail product, so cannot possibly be legitimate, yet somehow simply blocking any entries for it on Amazon is apparently beyond them.
Had many customers fall for it though, insisting they'll supply their own copy of Office only for us to inform them that 1) it isn't legit, and 2) we're not touching it.
