There are many things that will buy to eat but never eat some of them can be classified below:-
The first thing is utensils because we buy utensils to eat food but we never eat the utensils or you can say plates.
The second thing is the peels of the fruits because we even pay for the peels like that of oranges when we purchase them but we never eat them.
Well the third thing is the bread crumbs because like me I know many people who don't like to eat bread crumbs are the sides of the Pizza bread but we also pay for it and it is to be eaten but many of us jointed so I am including it in the list.
I hope this helps!
