Newegg still offers the Seagate 6TB Serial ATA 6Gb/s 3.5" Internal Hard Drive, model no. STBD6000100, for $299.99 with free shipping. (Amazon charges the same, although it ships in three to five weeks.) That's $50 off and tied with our mention from two weeks ago as the first discount we've listed for any 6TB internal HDD. It features a 128MB cache and runs at 5900 rpm.
