§46-2-507. Effect of seller's tender; delivery on condition.
(1) Tender of delivery is a condition to the buyer's duty to
accept the goods and, unless otherwise agreed, to his duty to pay
for them. Tender entitles the seller to acceptance of the goods
and to payment according to the contract.
(2) Where payment is due and demanded on the delivery to the
buyer of goods or documents of title, his right as against the
seller to retain or dispose of them is conditional upon his
making the payment due.
