Reba orders a pair of custom-made cowboy boots, C.O.D. from Home on the Range Western Wear. When the boots arrive, Reba pays the carrier for the boots, then opens the package, only to discover that the boots are the wrong snake skin color and three sizes too big. At this point Reba has no recourse; she should have known to inspect the goods before paying the C.O.D. amount. Reba is entitled to inspect the goods after payment (due to the C.O.D. terms) and she can reject the boots because they are nonconforming. Home on the Range can allege that Reba did not conduct a proper inspection; therefore, Home on the Range owes Reba nothing. Reba cannot revoke the acceptance, because the wrong color and size of the boots are not substantial impairments.
