Sometimes I’ll just become unable to eat a certain food anymore for whatever reason (taste, texture, smell, etc), and then it just sits in my fridge until it expires. I know I shouldn’t, but I feel bad for not eating it and it stresses me out a bit. Especially when I bought a lot of it to stock up.
You could buy unsalted butter, and turn it into ghee, then it’s shelf life is effectively infinite (or at least hundreds of years).
I’m able to finish a pack of salted butter before it spoils :)
