You just spent $347 at Costco. Two weeks later, three of those items go on sale. You'll never know -- unless you use Costcard. Costcard watches Costco prices so you don't have to. Scan your receipts after each trip, and we'll alert you when anything you bought drops in price within the 30-day return window. Then we help you get your money back. PRICE DROP ALERTS THAT PAY FOR THEMSELVES Every Costco member is entitled to a price adjustment if an item drops within 30 days of purchase. Most people never check. Costcard checks for you -- automatically, on every item, every day. When we spot a drop, you get a notification with the exact savings amount and days remaining to claim. SCAN RECEIPTS IN SECONDS Point your camera at any Costco receipt. Our AI reads every line item, price, and discount instantly. No manual entry. Works with long receipts, crumpled paper, and even photos from your camera roll. IMPORT YOUR FULL COSTCO HISTORY Already have months of Costco purchases? Log into Costco.com through our secure in-app browser and import your entire order history in one tap. Your credentials go directly to Costco -- we never see your password. PRICE CLAIMS MADE SIMPLE When a price drop is detected, Costcard builds your claim automatically: item name, original price, new price, savings amount, and deadline. Walk up to the membership counter with everything you need on your phone. No digging through old receipts. COUPON BOOK & DEAL TRACKING Browse the current Costco coupon book right in the app. See which deals apply to items already on your shopping list or in your purchase history. Regional deal tracking shows what's trending at your local warehouse. SMART SHOPPING LIST Build your list by voice, text, or straight from past purchases. Costcard remembers what you buy and how often, so restocking is one tap away. Share your list with household members. BUILT FOR COSTCO MEMBERS WHO VALUE THEIR TIME Costcard is not a coupon-clipping app. There are no ads, no points systems, no gamification. Just a clean, focused tool that watches prices and puts money back in your pocket. The average Costco member leaves $50-100 per year on the table in missed price adjustments. Costcard makes sure you don't. YOUR DATA STAYS YOURS We don't sell your purchase data. We don't show ads. Your receipts are stored securely and you can delete everything at any time. We make money by building a product worth paying for -- not by selling your shopping habits. Download Costcard and stop leaving money at the membership counter.
