When you're shopping for something on another site, the Assistant can show you the same or similar products that Amazon sells, along with any offers, ratings and reviews associated with the product.

2. Click the More results link on the left or right side of the alert to see what the Assistant has found.

3. The Assistant will display a page of products related to the one you're shopping for.

4. If you're interested in something on the page, tap the product to go to its page on Amazon's site.

If you find something on another shopping site you'd like to save your Amazon Wish List. Here's how to save them to your wish list, where you can see all the products you're interested in, both on Amazon and other shopping sites.

1. While shopping on another site, if you find a product you'd like to keep track of on Amazon, tap the Assistant button.

2. In the extension window, tap the Add to List tab and then when the product shows up, tab Add to Wish List.

3. To view your Wish List, on the Amazon site, from the Accounts & Lists menu, select Wish List to view the products you've added.

If the product is available on Amazon, the item on your Wish List will link to it. If the product is not on Amazon, the product will link back to the original shopping site
