Sold by zorotools via Ebay.
I don't know if tax is applied for you but no tax applied for me in Ohio.
Free shipping for no minimum. I would not hesitate. Good deal for C cells in my opinion. These rarely go on sale for less.
Just to be clear- I am not affiliated with the seller. I was searching Amazon and Ebay and found this deal.
C cell Link 12 pack $7.99.
Link to D cells 12 pack $8.70 thank you jbl01
9V link $14.39 12 pack.
Note: If you want or need more than $25 worth of batteries (mix and match), you can follow instructions in the wiki to save $5 off $25, or more for larger purchases through their direct website. Credit to EricT9060. post#38Link to zorotools direct deals
