Products appearing in more than one category/sub-category

I would like some of my products to appear in more than one sub-category, but am unsure as to how the inventory control would work by doing this. That's to say, by having a product in more than one sub-category I'm obviously not increasing my stock, but I need to create an 'alias' so that it can appear in another sub-category. Would someone point me in the right direction?
Thanks,

Go to Catalog>Categories / Products

Find your product and select the "C" to copy ... then specify "link"

perfect, thanks!

You are most welcome. Normally, I'm the one asking questions. I'm glad I finally knew an answer. We use this to put items into our "bargain bin," as well as their "normal" location, as well as items that fit into multiple categories.
