You can get a 20 pack of batteries for $12.99 and then they will mail you a rebate for $12.99 back. (You need to submit the information that will print on your receipt.) The rebate is not cash back, it is store credit from Staples.
There is a limit of 2 per customer.
There is also a coupon in this week’s ad for $5 off a UPS shipping order! That is an awesome deal if you have holiday gifts to send out.
You can read about how to register for Staples Rewards here. You will need to be a Rewards member to get the batteries- it is a free program.
Most stores will accept manufacturer coupons and there is a coupons for $1.50/1 Duracell Batteries, exp. 12-31-10 (RP 11/14/10 #2). So this could possibly be a moneymaker! I would call your store in advance and ask because each one will be a little different.
