if you are eating Out/take out i would probably stop, since its excessively expensive if done over a month/per month, although im not in a situation where food is costly. discount stores like grocery outlet, but the trick is eating the perishable as soon as possible, the ambient stuff you can save for much later especially things like beans and rice. as for veggies i usually buy coleslaw in those bags, since you can a little while before eating it, but fresh veggies often spoils quickly.

buying in bulk isnt useful if it expires too fast, unless you are buying things like canned goods.
