Wyo. Stat. § 34.1-2-512: Payment by buyer before inspection.

(a) Where the contract requires payment before inspection nonconformity of the goods does not excuse the buyer from so making payment unless:

(i) The nonconformity appears without inspection; or

(ii) Despite tender of the required documents the circumstances would justify injunction against honor under this act (section 34.1-5-109(b)).

(b) Payment pursuant to subsection (a) does not constitute an acceptance of goods or impair the buyer's right to inspect or any of his remedies.
