Western Digital 1TB Passport USB 3.0

Hi guys,

I need to buy an external hard drive soon as my current one is running out of space. I have decided to buy a Western digital 1tb passport USB3.0. I would prefer to buy this from a physical store rather than an online store. Currently the cheapest place that I can buy is at the good guys for $147, however they do say pay less pay cash. I was wondering if anybody could tell me how much less do you think I could pay for and secondly if I should wait for another month or so because there might be price drop in hard drives.

Also I may be thinking of buying 3-4 of these with my friends, how much do you guys think that I can haggle for when I price compare to other stores such as JB HI-Fi, harvey norman etc?

Many thanks
Steve
