Two thirds of working Americans buy their lunch instead of packing it, costing an average of $37 per week — or nearly $2,000 a year! Instead of relying on your wallet every day for lunch—why not make a little extra at dinner and pack up the leftovers for your next day’s lunch. It saves money and cleans out the fridge! Even if you don’t have leftovers from dinner, it’s relatively simple to put together a decent lunch at home for much cheaper dining out.
