Where to buy Duracell MN1300 batteries?

[C5Engineer 1170]

I installed an ELT and it says in the book to only use Duracell MN1300 batteries which are nothing more than the fancy D batteries. I googled it and amazon sells them but I dont' really want to pay shipping on something like that. I did a search on Walmart and Target websites with no luck. Anybody know offhand of a store like that where I could pick up 6 of these? Didn't realize that's what it took..that outta help move my CG back some.

yeah, just go grab some Da cdells off the shelf.  I got them at the local hardware store.  The A&P did not say boo about it when he checked it

Well I feel dumb for posting this... Duracell Coppertop D cell batteries say MN1300 right on them. Picked up an 8 pack for 9 bucks today at our Base Exchange.
