Affiliate Marketing - Amazon.com - Clickbank

hey guys, im trying to become an affiliate for amazon. But there is a section when registering that says "payee zip" and we don't have that in lebanon so what should i do to overcome that problem, i contacted them and they really weeren't of any help. so yea any suggestions?

also what alternatives to clickbank do you suggest since clickbank does not include lebanon as one of its countries.

thanks in advance
