You can get free batteries at Staples (in-store only). Through 4/30, you can purchase a 20 pack of Duracell Batteries (AAA or AA) and get 100% back in Staples Rewards. This is not a rebate. You will get it back in a rewards check.
If you use a coupon or previous rewards to pay for this, Staples will only give you back the actually amount you paid. Therefore, you shouldn’t use your rewards to pay for the batteries.
There is a limit of 2 per customer.
