Staples: Duracell 16-Pack AA or AAA Batteries Free after Staples Rewards

Staples currently has 16-Pack AA or AAA Batteries Free after Staples Rewards.  Here is a screenshot for your reference.  Note that you might have to go to first and enter your ZIP code in the store locator in order to see the weekly ad for it.  This is valid on SKU 581672 and SKU 618854 only.  Basically, if you purchase them using your Staples Rewards Membership Number (free and easy sign up), you will be issued a Staples Rewards Check for the amount you paid for those batteries.  If you will end up spending that money at Staples anyway, this would essentially make the batteries free.
