You must have money to burn, or use very few of these things. For the price of a single CR2032 in a store I can buy a pack of 50 from China including shipping. At least in my case they've always been just as good.
Then there are the legit ones from places like digikey but they require UPS ground shipping which is stupid for a single coin cell. I don't understand why those get lumped in with lithium ion batteries. Lithium primary cells are not a fire risk, particularly tiny little coin cells.
