I don’t need many. Thanks, Jerry
These are available virtually everywhere including Home Depot.
Battery Junction has a Black Friday sale now on Titanium brand CR123’s - 12 for less than $12.
eBay. I buy all my button cells, 9 volts, and other non-AAs/AAAs batteries on eBay. Price shipped to my home is much cheaper than buying them at a local store. Just make sure that the US seller has a lot and good feedback.
