Cake Group Buying is a sales activity in which a merchant sells a particular cake or a combination of cakes for a certain period of time at a special discounted price. Generally, during a group buy, users are required to pay a deposit or full payment in advance. Once the number of reservations is reached, the merchant will make and ship the cakes centrally. Through the cake group purchase, merchants can attract more consumers, increase corporate awareness and sales, while consumers can buy their favorite products at a lower price, enjoying the value of the benefits.
