Free Shipping Coupon Code

If you've been watching this book as a potential purchase, the publishing company just sent me a coupon code (APRILMAIL305) for "FREE SHIPPING," so buy away!  

This is what the email says that Lulu Press sent to me:

Use coupon code APRILMAIL305 at checkout, select Mail Shipping and receive the single book shipping cost free. Maximum savings with this promotion is $4.99. Print and tax amounts are excluded. You can only use the code once per account, and you can't use this coupon in combination with other coupon codes. This great offer ends on April 30, 2011 at 11:59 PM so try not to procrastinate! While very unlikely we do reserve the right to change or revoke this offer at anytime, and of course we cannot offer this coupon where it is against the law to do so. Transaction must be in US dollars.
