I needed a pair of 1616 coin batteries for the key fobs to the CR-V so I added a 5-pack to an existing Amazon order.
Amazon shipped them separately, in a huge empty box. (The box chosen, I think, because it was big enough for the Lithium: May Explode! warning sticker.)
I know everything about Amazon is terrible, but this seemed particularly terrible for whatever reason. ”The next time I need something like this, I’m going to walk up to the convenience store; even if it costs a buck more, it has to be better than an empty box shipped cross-country.”
The next time turned out to be just a week later, when (weird!) one of the key fobs to the Mazda started failing. I’ve got 1616s and 2032s, but not 2025s (and the Mazda forums suggest the clearance inside the fob is too tight to squeeze a -32 into it).
So I walked up to CVS, only to discover that they want $7.50 for a single battery. I walked back home and ordered 10 for $5.
