I received the following notification from Lulu.com
Enter coupon code EARLYSHOPPERAU305 at checkout and receive 20% off your order. The maximum savings for this offer is $100. Sorry, but this offer is only valid in US Dollars and cannot be applied to previous orders. You can only use this code once per account, and unfortunately you can’t use this coupon in combination with other coupon codes. This great offers expires on 11 November 2011 at 11:59 PM, so don’t miss out! 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.
The 20% discount (up to USD$100) is valid for all books from Lulu.com, this includes my books (do grab a copy if you have been waiting for a discount)
