Members need a deposit for pre-sale. According to relevant public information, membership pre-sale refers to some clubs, gyms, swimming pools and other institutions selling future services in advance to attract customers to buy in advance. In order to ensure customers' purchasing intention and credibility, many institutions will require customers to pay a certain deposit as an advance payment when purchasing membership, which can make the institutions plan their future services more confidently and avoid customers' temporary cancellation or default after booking. The deposit will generally be deducted from subsequent consumption or refunded when the customer leaves the meeting.
