Ebay , Amazon and Aliexpress have their own Affiliate programms and when you sign up there
you can see that you have options to use logos and many more things like banners etc.
They have mentioned that they will use these 3 as an agregator for the beggining while
getting more  ecommerce partners to sign up. After a while they can sign a special
contract with amazon , aliexpress  and ebay where they will use widely the incent coin
as a payment option and much more I guess.
