This extension adds an essential feature to the Sainsbury's online shopping site: sort by price per unit.
SainsburysCheapSort - sort Sainsbury's online shopping by £/item
This extension adds a feature which should be essential on the Sainsbury's online shopping site: sort by price per unit.
When comparing items of the same brand, larger packs are not always cheaper per item. Sadly, Sainsburys.co.uk does not allow sorting by 'cost per item'. That's where CheapSort comes in. At the click of a button it will sort the items on the page to show you what's really the cheapest.
Be aware, this extension can only sort items on the present page. I recommend you increase the list size to the maximum (100 at the time of writing) and filter the product search where possible.
In future I hope to add support for other websites. Feel free to contact me with suggestions and requests.

Does exactly what it says it should. Don't know why someone hasn't done this sooner. Please offer support for other supermarkets (Tesco, ASDA, Morrisons). Such a great idea!
