Affiliate Marketing Secrets

I’m planning to sell stuff outside the us, however is us made. I plan to buy it via Amazon, however to enter the Affiliate program they request a tax ID and is a not-negotiable feature. What do you recommend?

please! Like for example chitika or adsense need you to have a tax id. I want something without tax id.

I just started as an affiliate with clickbank and they asked me for my tax id, and i put in my social security number (They told me to). so what exacly do i need to do with this. please be detailed! thank you and please no rude comments!
