Yes as a matter of fact, we have both Sams Club and Costco (was Priceclub) out here.
I have a Costco maybe three miles away.
Used to carry their card and did buy their Kirkland brand batteries, many years ago.
Don't really shop enough now, to justify membership.
Have been in Sams Club stores; they're about the same, but again you need membership.
As for rechargeable batteries, I ran multiple sets of NiMh AA and AAA cells for my flashlights, some years back.
I got tired of the recharging, and the self-discharge.
They were often half-dead whenever I needed 'em, and had to swap batteries.
I'd never use 'em in remotes; couldn't stand the maintenance.
But glad to hear they've improved over the ears. :up
