Amazon Product Availability

Many products on amazon are unavailable but a date is given for when they'll be in stock. I've used AWS and got an XML reply but I can't find the date information anywhere. Is it possible to开发者_JAVA百科 get this information? Thanks.

NOTE: This is what i've got as a request, what should I alter?

You probably want either PublicationDate or ReleaseDate. You need to be sure that you're requesting a ResponseGroup that has this data in it. ItemAttributes has both, but there may be other groups that include them also.
