Best Affiliate Package for Our Affiliates?

NOTE: Not trying to 'pitch' our products here, just askin..

I own a nutraceutical/supplement company and I'm putting together an affiliate program. Do you have any suggestions for what to include in our affiliate package so we can cover the main checklist for supplement/nutra affiliates?

I'm sure most affiliates have their go to things they grab when looking to promote. So far, I have banners of all sizes, email autoresponder series, a couple landing pages and a 30 min video sales letter.

Any input is appreciated
