I recently bought Sunbeam CR2032 batteries at Dollar Tree in a blister pack of 2 batteries for $1.00. This is cheaper than I've seen in online stores, even when buying larger quantities. The batteries I bought a few years ago in quantity for a better price deteriorated and didn't reach their 2025 use by date. Now I can just buy what I need for a reasonable price. The store had other button batteries as well.
