op shop

noun1

1. •
   (Australia, New-Zealand) A shop, usually operated by a charity, to which new or used goods are donated, for sale at a low price.

   • Op-shops always have a rack like this - it′s where they put unusual stuff. Once, in a small country op-shop in New South Wales, I found a fabulous red ballgown made in 1952... but I digress. — 2007
