[oak perl] Discounts

[George Woolley]

Very recently, 
the topic of discounts 
has come up twice
in emails from group members.
(yesterday and today)

My understanding is that
using the DSUG discount code,
you can get a 20% discount on:
* O'Reilly books and also
      - No Starch books 
      - Paraglyph books 
      - Pragmatic Bookshelf books 
      - Syngress books 
* O'Reilly conferences.

For books
it's worth comparing prices.
Two money saving thoughts:
* second hand books
* books on CDs
