Light dry malt extract - where to get it

As a partial masher, every full sized batch of beer I do needs some malt extract added. I've generally used light liquid malt extract in the past (e.g. Black Rock or Muntons), but in my opinion, the better option is light dry malt extract (spray malt).
The Muntons dry malt extract is a bit expensive in my opinion, but I've found two stores selling Halcyon Light Dry Malt extract for good prices.

brewshop.co.nz - Currently $11.95 per kg
libertybrewing.co.nz - Currently $12.50 per kg

Obviously the shipping will dictate which one you go with.
brewshop seems to charge a flat shipping rate of $6.00, and they have no walk-in shop.
Liberty have a shop, so if you're local you can pick up. Otherwise, their shipping rates depend on location and total weight of the order.
