Just received an email this morning from Lulu. Get 10% off your purchase through the end of this month! All you need to do is enter the sale code when you check out: JUNECONTEST10.
Lulu is conducting monthly "sales contests" where the authors who sell the most books win cash prizes. Blatantly trying to drive traffic to Lulu.com, of course! What the heck - Didn't cost anything, so I signed up for June's contest. I received the email with news of the 10% discount this morning. All of a sudden the contest seemed worth entering.
My books at Lulu can all be found on this page, my Lulu "storefront": http://stores.lulu.com/mikeluoma
I was surprised enough by the discount that I wanted to share!
