How do you link to a specific item or can you do that in the affiliate program?
At the bottom of the page you will see two fields. You need to enter your Username and the URL to the item and that will generate a referral link.
I think every item page should have a referral link on the side so users can easily copy and paste it.
I agree with you. It sure would be nice if that code was there on the items page. I have seen things like that in other marketplaces
