Tesco Sort by Price Per Unit is a free Chrome add-on developed by Pez Cuckow. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools.

This add-on allows users to sort Tesco grocery products on the current page by price per unit, while also converting between different denominations. To use the add-on, simply install it and follow these steps:

1. Increase the maximum number of items per page to the largest available (usually 48) on any Tesco groceries page.

2. Locate the "Tesco Sort" icon in your Chrome extensions bar, located in the top right corner. It may be hidden in the extensions dropdown, but you can pin it for easier access.

3. Once clicked, the products on the page will be sorted by price per unit, from low to high.

This add-on provides a convenient way for Tesco shoppers to compare prices and make informed purchasing decisions based on the price per unit. It streamlines the sorting process and eliminates the need for manual calculations.
