Hm, their instructions seem to be missing the part where, before all that, you have to click their affiliate sign-up link, which would lead you to either log into or register for your own E-junkie account.
I think perhaps they meant the link in Step 1 to be their sign-up link, but they linked to the landing page their sign-up link would redirect to, rather than using their own, actual sign-up link. We can't provide you with that link for them, so you should contact them to bring this matter to their attention and get the proper sign-up link for their program.
