Usually when you get an offer from a seller there is a link provided to "view item" which takes you to the listing. Also there is usually a link to the seller. Unless you are viewing all this on your iPhone in which case I can't help you there I don't view Ebay over my cell phone (which is a droid actually) because I can't stand the mobile versions of some websites and the Ebay phone app is notorious for having all kinds of problems including not being able to link to somethings that would be useful.
