Should you be an avid Sainsbury's supermarket shopper and love earning the ol' Nectar points, you'll want to check out the Sainsbury's app for Windows Phone. The app, which is available for free, is a portal of information accompanied by quick access to the mobile version of the online store.
Unfortunately you'll not be able to do the weekly shop through the app, but Nectar details, special (and some exclusive) offers and a store locator is included. While more functionality would complete the experience, it's good to have such an app available on the platform.
Should you wish to order groceries online, you'll be taken to the mobile version of the supermarket's website in Internet Explorer, which will require a separate store login.
You can download the Sainsbury's app from the Marketplace for free. Thanks, Dan J., for the tip!
