Stacey's Annual License to Save Sale, 7/19-7/21
For three days only, Stacey’s Literary License members save 20% on everything (excluding periodicals) in the store. Their loyalty program is free to join --sign up at the Mezzanine Service Desk. In addition to this special sale, they give you a $10 certificate every time you spend $200 (it's cumulative not a one-shot thing), plus 10% off every book you buy every day.
And as they mention on their website, this Saturday, July 21st is Harry Potter Day -- might as well get that hefty hardcover for less.
