Pinduoduo's auction deposit varies according to the different products, generally ranging from 50 yuan to 500 yuan. Auction margin is a provision in auction activities as a safeguard for buyers to participate in auction activities to prevent malicious bidding or evasion of transactions.

Buyers need to pay the auction deposit before the auction starts, and the amount of the deposit will be settled with the commodity price after the auction is successful or will be fully refunded after the auction. Pinduoduo ensures transactions and maintains the auction order by setting up auction deposits, and improves the integrity and fairness of transactions. Therefore, when participating in Pinduoduo auction activities, buyers need to pay attention to the auction deposit requirements of specific products, and pay the corresponding amount as required.
