I bet there were MORE than 20 helpers - our sale has about 30/40 helpers I think - there will be lots of people behind the scenes you don't see. I DO know what you mean - in our sale, about 1/4 of the money is taken before the sale start, & I do think we should publicise that better, sometimes ... certainly lots of the good, big stuff goes to helpers.
But hey, the sale wouldn't happen at all if there weren't helpers (who give up their sat ams to help for free, remember) ...
So, volunteer to help out, spend 3 hours lugging tables around & unpacking other people's boxes, putting together clothing rails; and then spend 1.5 hours sitting at a till/helping in a hall, oh, & then spend 2 hours clearing everything back up, repacking everything into sellers boxes, lugging tables back, then sit around waiting for sellers who don't turn up until an hour after the hall's been closed ....
Actually, I quite enjoy it, but it is a faff, honest
