If you complete the survey at http://www.arrl.org/survey you will receive a coupon code good for $20 off any purchase at the ARRL shop.  If you already ordered Jack's http://www.arrl.org/shop/Microcontroller-Projects-for-Amateur-Radio/ you can pick up http://www.arrl.org/shop/Experimental-Methods-in-RF-Design-Classic-Reprint-Edition/ .  If you already ordered both this is a great opportunity to get either book or both for someone new to the hobby or who otherwise could not afford them.  The code works for members and non-members.
