Was shopping at Costco today and noticed that the deal for the Energizer Ultimate Lithium batteries were back. Regular price was $14.99. I did not see a rebate date, so most likely they are doing the $7 price until it is gone. There were several boxes left at the City of Industry Costco, Ca. Good Luck, and happy hunting.
Here are some links and post for reference
Target 12pk = $15.99
