2. When the order payment amount is greater than or equal to 3 yuan, you can choose to pay by installment;
3. Click online payment, select credit card installment payment, and select the number of installments.
Payment amount = total order amount+installment fee, where the total order amount is the amount of the order, and the handling fee is pre-calculated according to the bank rate for users' reference only, and the actual handling fee is collected by the bank and reflected in the user's credit card installment bill;
