If you have passed a Microsoft certification exam, you are probably an MCP. MCPs have been given a discount (I get the impression it’s for a short time) at Microsoft Press.
It’s 40% off print books and 50% off eBooks with a special discount code – a fabulous savings!
Log into Microsoft training and certifications site and navigate to Resources > More information > Microsoft offers for MCPs and you will see the codes.
I just successfully used it.
Thanks to Patrick Thomas (Microsoft) for letting us know!
