Wait for Sales, Then Stock Up
One secret to mega-savings is to stock up on sale items. Snacks are a great example of this. They don’t go bad, and once you miss a sale you’ll have to wait several months.
This might not work for everyone. Expert couponers often seem to score so much loot they almost require a 3,000-square-foot home to store it all in. A tiny Brooklyn apartment would be a sorry storage space for a year’s worth of Prego, Pull-ups, Popsicles and pet food, but if you have the space, it’s worth stocking up long term.
