An op-shop is a term used mainly in New Zealand and Australia for a charity or second-hand shop where people can buy used and donated items such as clothes, books, toys, and household items at a cheaper price. The term op-shop is derived from the phrase "opportunity shop." However, in other parts of the world, different synonyms exist for op-shop such as "thrift store," "charity shop," "second-hand store," "resale shop," and "vintage store." Regardless of the name, these shops offer great bargains and allow people to recycle and reuse items that would have otherwise been thrown away. They also raise money for charitable causes, making them a worthwhile shopping option.
