With regard to the removal of seller id from the listing page and putting another click away, this needs reversing, Ebay are adding another click to the sale process, To get to the cart should be no more than 3 clicks away,  (my it tutor told me that) now it 's 4 or 5 clicks away making the site feel clunky,

And not being upfront on who your buying from is it a business or a private i don't know lets click another button to find out then we will click back again,!
