Is the Vendee allowed to release advance payment?
The Vendor, in its sole and absolute discretion, may allow the Vendee to pay the outstanding unpaid principally, totally, or partially, upon such terms and conditions as may be imposed by the Vendor, provided that in case the Vendor allows payments in advance, such payments will not relieve the Vendee from paying the agreed monthly installments, the only effect of such partial payment being merely to shorten the terms of the contract. Payments of fractional installments will not be accepted.
