I'm going to use random related products on my site
But i will be changing titles on it so it sais something like "user who bought this product also bought this"

BUT as it is now it generates random products from all over the site, i want it just to generate within its own category, people will never belive that they are not generated randomly otherwise.
So if they could be generated randomly but within their own category that would be cool ..
