Regarding the 'perfect tender' rule, which of the following is FALSE?

• A. A seller who has not made a perfect tender of the goods has a chance to cure the tender if there is time left on the contract.
• B. The perfect tender rule does not apply to an installment contract.
• C. If the seller tendered nonconforming goods under a reasonable understanding that the buyer would accept the replacement goods, the buyer must allow for cure of the defective tender.
• D. Once a buyer has accepted the goods, the buyer cannot revoke his acceptance and return the goods.

Answer: (D)

Under the perfect tender framework, the buyer’s rights include not only rejecting nonconforming goods or accepting with a remedy to cure, but also revoking acceptance if a nonconformity that substantially impairs value is discovered after acceptance. The key is that revocation isn’t barred forever once acceptance happens; if the defect wasn’t discovered earlier and it substantially lowers the value of the goods, the buyer can revoke within a reasonable time after discovery. This makes the statement that a buyer cannot revoke after accepting the goods false.

The other points align with how cure and installment contracts work: a seller can cure a nonconforming tender if there’s still time left in the contract, giving a conforming tender within that period; the perfect tender rule isn’t applied in the same way to installment contracts—which allows for nonconformity in individual installments rather than treating the entire contract as strictly tendered at once; and when the seller tendered nonconforming goods under a reasonable belief that the buyer would accept replacement goods, the buyer is expected to allow for cure of the defective tender.
