Payment by buyer before inspection

(1) Where the contract requires payment before inspection non-conformity of the goods does not excuse the buyer from so making payment unless (a) the non-conformity appears without inspection; or (b) despite tender of the required documents the circumstances would justify injunction against honor under this subtitle (section 28:5-109(b)). (2) Payment pursuant to subsection (1) does not constitute an acceptance of goods or impair the buyer’s right to inspect or any of his remedies.
