Today I saw a seller on Amazon selling a new 4TB Red for $124 with free shipping! Quite a few flags on this, but I thought I would post anyway in case there are some brave souls out there. The seller (Outlet Wearhouse, even the name is suspicious) has only 1 review, and is from New York.. I don't know the details of the amazon guarantee, but that might make it worth the risk... for others, not for me..

Good Luck,
