I want to see how elegant a solution I can get in a functional language, given that the problem description is not really elegant at all. It has a few annoying exceptions to the normal rules, typical of what one might get in a real specification from some client.

After taking a look at other solutions, I feel like I will have to explain myself, so I’d better do that without prompting :)

 - nothing was said about meaningful error messages, so I didn’t bother.  - I had decided against defining constants like `supplier_markup_percentage_modification`    separately; `PremiumSupplierIDs` and markup table are defined locally in the `calc`    function, too. The latter two issues are fixed in the next version, as someone    may consider them to be against elegance.  - surprisingly, all solutions use explicit comparisons to determine the product    category. While it is okay for continuous ranges of codes, it doesn’t scale and    not really elegant. Fixed as well.

Thanks, I've merged this. Had a quick look at the code, I like it :-) -- http://pauley.org.za/ http://twitter.com/apauley
