  1. I received an email about this DEVREF discount. When I attempt to order one of the books listed in the email, “Microsoft Visual C# Step by Step, 9th Edition”, the system does not allow me to enter the DEVREF discount code for that particular Book or eBook. This is a very misleading email!

    1. Thanks for contacting us. Discount code DEVREF applies to all books and eBooks in the Developer Reference Series. After adding Microsoft Visual C# Step by Step to your cart, please click the Proceed to Checkout button to see your order summary. If the discount code screen does not automatically appear, click the blue “Edit” button next to Discount Code section in the left column, type DEVREF in the “Enter a new discount code” field at bottom of screen, and click Submit to apply discount to your order.
