Before it breaks | Buy consumables that are about to wear out at the cheapest place

A service that finds the true lowest prices for consumables you can't afford to run out of, such as detergent, diapers, water, and beer.

How to Use
Print a QR code and place it where you store the consumable—on your washing machine, shelf, etc. When you're running low, just scan it with your smartphone. It searches across Rakuten Marketplace, Amazon, and Yahoo! Shopping, displaying results sorted by the lowest "effective price per 100g (or per unit)" after deducting shipping costs and point rewards, so you can buy directly.

Features

• Compares based on effective price after deducting shipping and points, not the displayed price
• You can compare different quantities and bulk purchases by converting them to unit prices
• Prices update every morning
• No membership registration required

Perfect For

• People who want to buy daily necessities as cheaply as possible but find it tedious to compare three websites each time
• People who want to eliminate the problem of "realizing too late that you've run out"
