Recommendation for Affiliate Website

I am currently running a blog that gets around 30k to 35k unique hits a month and around 60k to 70k pageviews per month. The blog is a celebrity news and information blog. The celebrity is heavily into working out and has a cool line of clothes coming out. I have set up affiliate marketing accounts with Clickbank, Linkshare and Zazzle. These sites are ok but im looking to increase my monthly revenue to something more proportional to my traffic. I have put vitamin affiliates and clothing affiliates so far. None have netted that much.

Does anybody have some good affiliate recommendations to help increase the revenue my site is generating. It has the potential to make 3-5k a month with the amount of traffic its getting. I want to make this happen.

Any thoughts?

Would anyone sign up for an email list?

Here's what I do on my blogs with traffic.

1. Signup at feedburner
2. Put the feedburner email opt-in box on your blog
3. Periodically make promotional posts or put text / affil links in the bottom of your posts and let Google (feedburner) mail your members for ya - 100% inbox.
