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

http://ecs.amazonaws.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&
MerchantId=All    

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.

	Tip
	Be careful not to introduce spaces before or after the commas in the comma-separated list of ItemIds.
