That sucks Yeasty! Delivery prices in Australia are about half that

I'm not sure how successful bulk buying is
unless you have a mill and setting a mill up can be quite a job. Mind you, a lot of shops here will crush your recipe and then vacuum seal it. As long as the seal doesn't puncture (which sometimes happens) the brew should stay fresh for a long time.
When first starting out bulk buying, there are some base malts that can work well for both lagers and pale ales (Galaxy malt in Australia is one) which saves you having to buy two bags. As time goes on, you'll find your collection of specialty malts increases. Like hashie, I keep mine in air-tight containers but my base malts don't get this luxury. Grain lasts very well in a dry climate though.
Hops seem to build up over time as well. These I keep in zip-lock bags and put all the zip-lock bags inside air tight containers in my freezer. These seem to last very well.
I think you really have to do some planning ahead when starting out on bulk buying. In other words, plan your next four or five brews and order everything for them and add a bit so as you slowly build up a bit of a store which will later let you brew more ad hoc. I never did this and so was always having to drop into the shop for a bit of this and a bit of that. This was no problem for me as the shop was close by or, if getting stuff mailed, I'd "conveniently," think of something else to buy to make the postage worthwhile

When you do plan your first five brews, don't be scared to change some of the grains or hops to substitutes that will work over a higher number of recipes. I remember making sure I always had exactly the same hop as in a recipe. Once I accidentally used Saaz instead of Hallertau in a Schwartzbier. It ended up that I couldn't tell the difference

. Now I am a bit more flexible.
While I have a handy store now of grains and hops, I still have no auto-syphon in stock
