Where offers and prices come from
CostChirp checks product item numbers and reviews retailer sources before adding offers. It does not list every Costco product or check every warehouse continuously. Check the source and date shown with each offer or price.
Online and warehouse prices may differ. Past prices apply to the date and shopping method shown. A coupon discount does not tell you the final price. If no price is shown, CostChirp does not know it.
Fictional sample products and prices are labeled. They let you try the site and are not real offers.
Item numbers, sizes, and locations
A product page may group several sizes or options. Each item number has its own prices and sale history. Check the package size before comparing prices, especially if the packaging has changed.
A national sale does not guarantee that your warehouse has an item in stock, charges the same price, or offers the same discount. Check the official promotion terms and retailer before buying.
What is not available yet
You cannot buy Premium, receive personal alerts, or sync your shopping list between devices yet. The phone app’s receipt scanner is not available to use. This website does not let you upload, scan, or enter receipts.
Sale forecasts are unavailable. They need enough comparable sale history and testing before CostChirp can offer them. If released, forecasts will require Premium and will not guarantee accuracy or savings.
