Can We Post Affiliate Codes?

I am new to this site. I've read the terms and conditions but couldn't see an answer so hoping you can help me.

I have been using products from a small NZ based natural health company for a while. Just recently they have offered me a code that allows friends and family to get a discount (with each sale I also receive a small commission).

I believe in this company's products and the discounted price makes it a reasonable deal over the retail cost.

Am I allowed to post the code to this website?

Thanks!
