During Thanksgiving weekend, the Kindle version of Double Jump is on sale. It started off at 99 cents in the early hours of Thanksgiving day, and will increase incrementally all weekend. Keep in mind that the Kindle version will always be 99 cents to someone who buys the paperback version by using the Amazon MatchBook program. You can save on the paperback version this weekend by using the code BOOKDEAL, which will net you 30% off. Best of all, it’s all automated and digital and doesn’t require anyone to brave the cold to face the bloodthirsty throngs of consumerism.
