Variation Parents

The abstraction of the variations is called the variation parent. The title element of the variation parent names the variations, for example, "Long Sleeve Classic Pocket Tee". Because the parent ASIN is an abstraction, it cannot be purchased, that is, it is not associated with an offer. The following request uses the Offers response group in an ItemLookup of a parent variation.

Copy Service=AWSECommerceService& AWSAccessKeyId=[AWS Access Key ID]& AssociateTag=[Associate ID]& Operation=ItemLookup& ItemId=B00006XYAB& IdType=ASIN& Condition=All ResponseGroup=ItemAttributes,Offers &Timestamp=[YYYY-MM-DDThh:mm:ssZ] &Signature=[Request Signature]

As you can see in the following response snippet, no offers are returned.
