<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">retail transactions</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 sales that I've seen before include "a feature of Boxing Day?" , "Cheap offer periods" , "Opportunities to sell" , "Occasions for buying at reduced prices" , "commercial exchanges" .)
