Another decent price for a portable hard drive. However, I think it's value for money if you have the red credit card that provides a further 10% off till March.

I believe this is the best price in NZ history for portable 2TB hard drive. Best price in 2015 If you have managed to obtain the Warehouse Money credit card, you'll get further 5% off
