What to include/remove on a public order page

Been looking on dribbble for inspiration for my website. I like things to look beautiful so I’m stuck on a partial order page (public with a unique url – same as github private gist):

Inside those cards will have product images but that will be added during beta testing etc. If someone sends you a url for payment for a product, what would you expect to see? For me, that’s what I expect.

Since it’s a private url, but only you will know the url (seller and customer), I’m not sure what information to be “public”. So far a seller’s information will always be public but what about the buyer’s details, should I include it? I could include the buyer’s email address in the card details area for stripe:
