My sister showed me an app today called "too good to go". It's basically an app where bakeries, restaurants and other venues let you register to pick up bags of today's food for almost nothing before the have to throw it away. She picked up a huge bag from a local bakery yesterday filled with bread, brezen, croissants and other stuff for just 4€ and put it into her freezer.

Very cool!! Not sure if this is a thing outside of Germany.
