Newegg has a 1-day deal (while stocks last) on Western Digital Blue 1TB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drives for only $55. They may sell out at that price.

Dang, I could have used another drive for raw video footage, don't got the money right now though.
I only have 375 GB free on my current drive. :-\
I'll have to compress and upload my current raw footage to free up some space when I get the chance.
