Lulu.com is having a one day sale today for 25% off any order up to $750 (!) and 30% off orders above that.
It can be hard to find things of interest on lulu.com given their search system. My recommendations are to pick up back issues of Quettar, and definitely check out the books from Mark T. Hooker (Tolkienian Mathomium and Hobbitionian Anthology). Let me know if you find other interesting titles!
The fine print from Lulu.com:
Enter coupon code CYBER305 at checkout and receive 25% off any order. The maximum savings for this offer is $185. Enter coupon code MONDAY305 at checkout and receive 30% off your order of $750 or more. The maximum savings for this offer is $750. Sorry, but these offers are only valid in US dollars and cannot be applied to previous orders. You can only use these codes once per account, and unfortunately you can't use these coupons in combination with other coupon codes. These great offers expire on November 29, 2010 at 11:59 PM PST, 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.
