they are buy one get one free so you get two packs. In store pickup is free
. You have to put two packs in your cart, one will be $6.99 and the other
will be $0.00. You can also mix and match. Buy a AA pack and get a AAA
pack free.
These are their Toys R Us brand but according to a reviewer, these batteries
last 5 minutes less than Duracell batteries, so these are quality. They
did this deal early last month and it's happening again.
