Categorizing items within a page

Hello,
I’m trying to create a few pages of affiliate links (3). these items would be my favorite T-shirts and the pages would contain all the links (as images). Each page would be: Men, Ladies, babies etc.. But i want each item to also be organized within categories so people can click on for ex. “political”to see all the political T-shirts. The thing is that WP does not naturally work like this. The only way is to put each affiliate link on one post and have a group of posts. I don’t want that though. I would really like them to be shown in pages. So my question is: Is there a plug in or a way to make this possible? I’m pretty sure this is not a radically new idea and someone (or many people) have done this before. Any info or advice from anyone would be greatly appreciated.
Thanks a lot,
Justin
