CostLow 

CostLow lets you see your warehouse's clearance deals, get instant alerts, and save with automatic price-drop checks. If a Costco price ends in .97, it's a clearance item that won't be restocked. Clearance items are unadvertised, vary by location, and won't last forever. See a list of all clearance deals at a selected warehouse. Sort and filter by category, off, 10 and under, and more. Snap your receipt and CostLow reads every item and price. We monitor prices for 30 days and alert you instantly when a price drops, so you can get cash back.
