How much money are you spending on wedding favors?

My fiancé wants to do mini lanterns which I’m going to double as table decor. I’m thinking of just doing one per family and putting 3 or 4 on each table. Those are about $5 each. Then, for guest table assignments im thinking about doing sanddollars and putting a magnet on the back of them so they can also be reused and used as favors. My mom wants me to do the sanddollars but they are around $1.25 each. I was going to pick shells off the beach, pain them and use them. Then, our caterer throws in a hot pretzel and waterbottle that they give guests on the way out which they said people use as favors themselves! I think this is all too much and may just veto my mom and still do the shells. All these little expenses are adding up. How much are you all spending on favors?
