Walgeen's / unavailable battery
I was looking for a small round battery to replace one numbered 196 from my thermometer. There is a handy device by the round batteries where you can find one that matches yours. I found that battery #392 was a match. However, there wasn't one on the hooks. The manager at Hampton Village was very helpful. He looked on the computer and said their store didn't carry that size, but gave me the name of one that did. I don't understand why every Walgreen's doesn't carry all the battery sizes.
