Re: Google Shopping Feed
It's getting complicated. You can specify one Google category for the entire feed or you can specify a cross reference of your category to Google category for each of your categories. Most of our clients just go for the one category for all products since it is a lot of work for the client to build the cross reference. The cross reference will be applied when the feed is generated.
Of course this only applies to our Google feed which is a subscription based feed (not a mod). If you're interested contact me at the address below.
