Staples Free Batteries

Reposting this as the deal as it is good through December and this is a new week. (Thanks Mom)

Between today and December 26, 2009, you can get $12.99 in Staples Rewards (free to join - sign up right at the store) when you buy a 20-pack of Duracell batteries for $12.99.  Best of all?  There is a limit of 2 20-packs per week!  By the time Christmas rolls around, you should have plenty of free batteries!
