Lowes home improvement stores also carry larger packs of batteries and are much cheaper than Walmart.
I like to buy my at Sam's club they are a lot cheaper, 14 dollars but there are 48 battery in a pack and nobody has them that cheap.
They vareity of them you need to make sure witch one you like and they come 2 back 4 back or 8 back even 16 back.
I buy my batteries at the dollar tree...and have never had any problems with them.
It depends on how many you want to buy
