Vendor v. Buyer: Enforceability of Original Payment Terms Over Failed Installment Agreement

A vendor sued a buyer for the price of goods delivered under a contract that stipulated payment was due within a set period after delivery, but the buyer argued the payment terms were nullified by a later agreement for an installment plan. The court affirmed the lower court's decision against the buyer, reasoning that the subsequent installment agreement, which was conditional upon the buyer providing a specific form of security that was never delivered, did not legally supersede the original, unconditional payment term, meaning the original due date remained enforceable.
