Spend a little now, save a whole lot later — that's the genius idea behind these smart products on Amazon that reviewers swear save you at least $50 (and, in many cases, a whole lot more than that). You'll find a split end repair hair serum that extends the length of time between salon appointments, a Shark Tank-approved spatula that gets out every last drop of peanut butter, a smart plug that lets you run your appliances on a schedule, and so many other money-saving goodies. So don't be afraid to spend a little — these products will pay for themselves in no time flat.
