Was looking for a 2tb hard drive for my Xbox, found this at an online store, haven't bought from them before. Not sure when the deal expires.
Went to Officeworks and with the price beat got it for $94.05, copy of the receipt in case someone needs it;

Product code is different on Officeworks site but under Product Specs the part number is the same.
This is the cheapest I've seen at the moment.
I believe WD 2.5" HDD also known as the portable ones, are USB soldered on to the PCB of the HDD. Therefore even if you remove it from the case, you cannot plug it directly into SATA.
