Sale of lots (7)
I believe the answer is:
auction
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">sale of lots</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for auction that I've seen before include "Lots are sold here!" , "A lot will be seen in this" , "Public sale by bid" , "Offer to bidders" , "Competitive sale" .)
