Seagate 1TB 7200RPM 32MB Hard Drive for $79.99 shipped after code EMCLXNS46.  Here is a screenshot for your reference.  Note that it is in OEM packaging, which means no pretty retail box and marketing materials.  For the technically inclined, it may be interesting to know this is the newer 7200.12 model, which has been revised to utilize a 500GB/platter design, the highest density currently available for reduced power consumption and better performance.
