Personally I find that with so many categories and sub cats it can get a bit confusing searching for some items, for instance if you put Zips in search you get everything shown with Zip in the title including comics because the Zip code is included when all you want to is A ZIP but you have to scroll through the lot or just give up before you start and for someone new to the site this could prove infuriating, lets face it you go the the other sites put in zips and zips is what you get, even if you Google zips you get zips and nothing else! I had trouble finding my own items in a simple search.
