I've just purchased a copy of Unity iOS which I got for a 20% discount by using the rebate code "UTPRO1011". Store price is $400(US), and I got it for $320(US) which is like $333(AU). I think the deal is initially for the pro license, but it seems you can use it with any license. This offer ends on October 6 so you'll have to get in quick.
The other great thing about this deal is that if and when I plan to upgrade to Unity Pro and / or iOS Pro in the future, I will get a deduction of the cost of Unity iOS $400(US) from those licenses, and not the $320(US) which I paid. Of course, you'd save a whole lot more by purchasing both Pro and iOS Pro instead, but it's a big chunk of cash to pony upfront ($3,000(US)).
Also, there's a special offer at the moment for Ürban PAD. Ürban PAD is a procedural city/town/building generation tool that's worth $700(US), but they're dropping it down to just $29. It exports models to all your favourite modelling tools, as well as Unity and UDK.
If they reach their target pre-order goal before the deadline (October 3) then they will process all the orders. If not, they'll refund your purchase. One of the developers posted about the deal at the Unity forums saying that it's looking likely to reach it, so if you're an indie developer and you're after a useful tool, $29 is certainly a nice price.
