In the UK there are a range of Apple prices_
1. The standard price
2. The student and teacher price - equivalent to 5-9% discount, depending on which bit of kit you're talking about.
3. The NUS student price (NUS = National Union of Students), which is just a bit better than 2 above, ie around 6 to 10%.
4. The price that schools and colleges pay for Apple equipment. Not sure, but I think this is the same as 3 above, but obviously without the 17.5% VAT.
5. I think there is also a different price structure for businesses, but I've never looked into this.
As far as I know, Apple only discount their own hardware and software, so a student would pay the same price as anyone else for, say, a Kensington mouse or Wacom tablet.
