HEB has some yellow coupons in store good through 12/1 that makes 2 packs of Energizer 4 pack AA or AAA just $2 each wyb 2.
Be sure to find the packs with the $4 Bunny Bucks back when you buy 2 packages with codes. I picked up 2 and was able to redeem for $4 back via Paypal or check.
Paypal you will get paid back quicker so be sure if you want to get paid via paypal you use that email when entering your info as that is where the paypal will get sent:
Limit 4 $4 offers per person/address/e-mail.
