Ultimate consumer (3,4)
I believe the answer is:
end user
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">ultimate consumer</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for end user that I've seen before include "not interested in the beginning?" , "One showing ultimate possession" , "Ensured (anag.)" , "last link in the chain" , "Product's final owner" .)
