Return New Releases from Shopping Cart Items

To encourage add-on sales, display new releases that are similar to items in a customer's shopping cart. You can use the CartNewReleases response group, which works with most cart operations.

The CartNewReleases response group returns the ASINs and titles of the top five new releases in the root category of the item specified in the cart operation. For example, if you add a television to a cart, the top five new releases in the root category, electronics, are returned.

In the following request, the item B000062TU1 is added twice to a new shopping cart.
