As I stated in my best cigar books post, proceeds from sale of books would be given back to one lucky reader in the form of a gift certificate. Here is another one. It is a gift card for $25 that can be redeemed on Amazon.com (doesn't work on .co.uk or .fr).
Below is a widget that allows you to participate in the contest. You can enter with your Facebook account or e-mail, then earn extra entries by doing some social sharing (Tweeting, liking on Facebook, etc.). What's cool is that you benefit from sharing the contest - every time somebody clicks on a link you shared, you earn an entry. So instead of diluting your chances to win, you're actually increasing them!
This is all experimental, so your feedback is welcome in the comments below.
The winner will be announced in one week, next Tuesday. Enjoy!
