Plunging prices (not toilets; lets clear that up now) every day for 20+ years. Price Plunge deals can save you 75-80% off retail, easily. The trick is to act fast: exactly one product is offered at a bargain-basement price each day; when it’s gone, it’s gone. Due to the nature of their business model, Price Plunge coupons are not on the menu. But you can earn Plunge Points with purchase.
