sales
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">auctions</span>' is the definition.<br/ ><span class="explanation-format__explanation">(auction is a type of sale)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for sales that I've seen before include "Income received for goods and services over a given period" , "a feature of Boxing Day?" , "Periods when shops sell goods at discounted prices, bargain times" , "Opportunities to sell" , "Cheap offer periods" .)
