I love a good battery deal. Paying for them online (and having your husband pick them up on his way home from work) makes it even sweeter.
I could type it out, but I simply did exactly what Life as Mom did. Details, directly from Staples, are here.
Each week from now through December 26th, I'll get $26 worth of batteries for a grand total of $1.56 in tax. Love it.
Edit to add: I've read this through several times and the offer is valid for each Staples Reward customer - I can't find any prohibition on multiple family members doing the deal. So I just signed Stewart up and did it again - wheeee!
