This is my first deal posting, so be gentle! 
If you pre-order Mental Floss' new book - The Mental Floss History of the World: An Irreverent Romp through Civilization's Best Bits (Hardcover) - you can get a 6 month subscription for free (that's a 3 issues). Mental Floss is a great magazine (and rarely available at book stores).

The book is 16.29 (with free shipping with 25.00+ orders - I ordered some kitchen towels I needed & some metal wire for 55 cents as filler).
A 1 year (6 issues) subcription is normally about 22 bucks - so this 6 month/3 issues is valued at about 11 bucks (more if you were able to find it & buy it at a store) and the book for 5 bucks.
Check out their website before you decide to buy - I saw this magazine for the first time at a friend's house and immediately enjoyed it. Great magazine & a lot of fun - check out their website before you commit to buy!
Enjoy!
