We're not really trying to sell batteries, it's more of a service -
just something we offer if you're buying a product that needs batteries (such as heated gloves or outdoor clocks).
Now, some shops might see this as an opportunity to charge a bit more for their batteries (guessing that the customer
isn't going to bother checking prices on those extra batteries when they're already buying something).
But we don't see it like that. We charge what we think is reasonable for our batteries, based on how much we're paying
for them.
