Calendars.com takes up to 50% off select 2013 wall and desk calendars. Plus, score free shipping with no minimum purchase required via coupon code "FS1161". That's the best sale we've seen from Calendars.com since February, when it took a flat 50% off 2012 calendars.

Update: You can apply coupon code "SPOOKY15" for an extra 15% off. It won't stack with the above code; however, it will yield stronger discounts for orders of $25 or more. (All orders over $25 automatically receive free shipping.)
