Returning New Releases From Shopping Cart
Items
A great way to spur add-on sales is by presenting customers with newly released items that are similar
to items in their shopping cart. The CartNewReleases response group enables you to do this. This
response group 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, when adding a television to a cart
the top five new releases in the root category, electronics, are returned.
In the following request, an item is added twice to a newly-created shopping cart.

Sorting by Popularity, Price, or Condition
The order in which you present the items returned is important to your customers. Often, they would like
to know things, such as, what item is the least expensive, which is the most popular, which items are
collectibles? Product Advertising API provides this functionality using the Sort parameter in
ItemSearch
requests.
The valid values for the Sort parameter in
ItemSearch
requests vary by locale and search index. For a
complete list of valid values, see
ItemSearch Sort Values By Locale. (p. 314)
Some of the most common
ItemSearch
Sort parameter values are described in the following table.
Description
Sort Parameter

The three versions of this value are equivalent in meaning but are
valid in different search indices.
pricerank, price, +price

but are valid in different search indices.
