One great way to stretch your pennies and be frugal is to freeze stuff, and not toss leftovers before they have truly gone bad. Here's a good chart I found from Good Housekeeping called "How Long Will It Keep?" in the freezer. Everything from milk to bacon to cheesecake is on this list! I hope you can click on this picture and enlarge it - I really don't have the time to type up every single thing on this list, and I can't find this chart on the Good Housekeeping website for some reason.
