No affiliation. They have excellent prices on bulk battery buys and regular sales on top of that. I recently got 25 CR2032 cells, which I use in my red dot sights and are the backup battery for my PDA, for $13 delivered. I got my first Surefire 6P today and ordered a dozen CR123A batteries for $25 delivered. I've used the 6 volt version of this battery in my AF cameras for a couple of years with good results.
Anyway, it's just a site worth checking out for batteries if you're price checking.
Deliveries have always been prompt, and I've never had any problems with them.
