Leo Liu explains that most online shopping is about transferring funds and organizing postage or delivery, with both buyer and seller interacting solely online, neither ever really likely to meet the other. But online group buys require meeting in person, so most buyers will join groups near their homes, workplaces, or other places they frequent to make it easier to pay for and pick up their purchases.
劉謦豪解釋，一般網購主要透過匯款、郵寄或宅配等方式交易，買賣雙方的交流僅限於虛擬世界，彼此常是老死不相往來；但網路合購通常需要面交（當面點交），所以網友多半會加入住家、辦公室或活動範圍附近的家族，便於向主購取貨付款。
