1. What does it mean?
In shopping, 공구 abbreviates 공동구매. It refers to people buying through a coordinated offer, often organized by a community, creator, or seller. It need not involve friends physically buying together.
Also written or said as 공동구매, gonggu
2. The nuance
공구 also means tools in another context. A group-buy label does not itself guarantee a discount, authenticity, stock, or delivery date.
3. Examples
“동아리 티셔츠는 공구로 주문했어.”
We ordered the club shirts through a group purchase.
“공구 마감 전에 구성과 배송 일정을 읽어 봤어.”
Before the group-buy deadline, I read the package details and delivery schedule.
