Yesterday, I went to AX-MAN in Crystal, MN. I discovered they have generic (plain white with no brand at all) 123A Lithium Batteries for $1. They also have LR44/A76 batteries for 10 for .95! I did stock up and the batteries are great.
They also have a walking stick/mono-pod that is very nice for $12.95 I've used it for walking in the snow and also as a mono-pod.
They also have other batteries.
