Performing Multiple ItemLookups in One Request

The other way to execute multiple ItemLookup requests in one request is to use a comma-separated list of ItemIds, for example:

http://webservices.amazon.com/onca/xml?
Service=AWSECommerceService&
AWSAccessKeyId=[AWS Access Key ID]&
Operation=ItemLookup&
ItemId=B00008OE6I,B35987036I,B0002546I,B25468OE6I,B09788OE6I,B00453OE6I&
IdType=ASIN&
ResponseGroup=OfferFull&
Condition=All&
Timestamp=[YYYY-MM-DDThh:mm:ssZ]
&Signature=[Request Signature]

The preceding example shows six ItemIds in the request, which means ItemLookup will be executed six times, one for each ItemId. You can specify up to ten ItemIds.
