CartWise: Unit Price Sorter for Instacart

About

CartWise adds clear unit-price badges to Instacart product cards so frugal shoppers can compare real value at a glance.

It detects package sizes, multipacks, count-based items, ounces, pounds, fluid ounces, and estimated-price meat sold by the pound. Use the floating controls to scan the current results, sort low-to-high or high-to-low by comparable unit price, and restore Instacart's original order.

Useful for:
- Finding the best cereal, drinks, paper goods, dairy, and meat values
- Comparing cents per ounce, dollars per pound, fluid ounces, and price per item
- Avoiding mental math while grocery shopping
- Keeping a unit-price sort sticky as more items load

CartWise runs only on Instacart pages. It is not affiliated with Instacart and does not collect or transmit personal data.
