Sure, but I just wanted to point out that some of us do not have freezers that can store a lot of food. Whenever I see people being like "just freeze the leftovers" I look at my freezer like "how?". If I put a bag of beans, a bag of ice and some springrolls in there, it is filled to the brim.
People shouldn't assume that everybody have tons of space to store perishable foods. That's all.
In my household we usually go for small packs of food when we shop groceries. Meats and vegetables etc. We go for small sizes because we don't want to end up throwing out food. It's not cheaper, but it is less wasteful in the long run.
