CR2032

I managed to find a blister pack of these yesterday at the supermarket. I can get them from Amazon for a little less, but it's more useful to have them now. My wife's bike now has it's light/reflector reinstalled and functioning again.

I need to place an order soon, I want a SSD for my laptop and a new passive graphics card for my desktop computer (while they still make them), so a few extra batteries as well at the same time won't hurt.
