Amazon has 20-pack AmazonBasics Alkaline Batteries in AAA for $3.08 or in AA for $3.38 when you checkout via subscribe & save. Shipping is free with subscribe and save or amazon prime! This price may not last long so grab this deal while you can!
And the reviews are really good too! I am picking up a pack of each AA and AAA because we ALWAYS seem to need batteries for something in this house!
**As with all AMAZON deals the prices may change at any time, so make sure to double check your prices before purchasing**
