PBtech currently has a deal that if you buy 1 Razer Nabu X, you get another free. Current price is the same as competitors, so it's a good price if you want two.
Limit 1 deal per customer, delivery from $5.75.
If you want a cheaper alternative and don't mind using Youshop, you can get the Pivotal tracker from Pivotal Living for only $12usd + $4usd shipping + youshop shipping (around $12NZD). Catch is the band uses a yearly subscription (12usd a year)
