My book Writing High-Performance .NET Code is already pretty inexpensive by programming book standards, but I’ve added a new deal. If you want to do get both the PDF and the EPUB, you can get 25% off the entire order, which basically makes one of them over 50% off.

Just go to http://www.writinghighperf.net/buy, add both formats to your shopping cart, and use the 25PERCENT discount code at checkout to receive the discount.

Check out my latest book, the essential, in-depth guide to performance for all .NET developers:
