Mr.Wang , we haven't discussed the mode of payment .   You know Mr . Forster , this is a really large purchase . I am afraid we can't pay off at one time . We have to pay by installment .   Do you mean you prefer a deferred payment ?   Yes , Mr.Forester .   When do you start the payment then ?   We'll start our payment in half a year and the total amount will be paid off within 2 years by three installments .   We can accept that but you have to pay the interest .   All right .   Shall we sign the agreement now ?
