Your receipts can point to better timing.
Haul Math is a private shopping companion for Costco members. Import receipt files you choose, then match exact item numbers to current U.S. warehouse, online, and weekly offers. See what you spent, what you buy repeatedly, and where a current offer may be useful.

ON-DEVICE BY DESIGN
Receipt parsing, receipt history, saved products, matching, and local usage counters are processed on your phone. Haul Math does not ask for your Costco password and does not upload receipt history to Haul Math servers. If Android backup is enabled, Android may include your Haul Math receipt archive in a device backup or device-to-device transfer. You can also export a portable backup yourself.
OPTIONAL HAUL MATH PLUS
Plus unlocks the full current offer catalog, all exact receipt matches, full possible price-adjustment details, repeat-buy history, Saved, and local deal alerts. Google Play shows the final localized price and renewal terms before purchase. There is no free trial. You can cancel in Google Play.
IMPORTANT
Possible price adjustments are informational. The retailer makes the final decision on eligibility. Offers, prices, inventory, dates, and availability can vary by location or channel. Haul Math never guarantees a saving or adjustment.
