Terms with respect to which the confirmatory memoranda of the parties agree or that are otherwise set forth in a writing intended by the parties as a final expression of their agreement with respect to such terms as are included therein may not be contradicted by evidence of any prior agreement or of a contemporaneous oral agreement but may be explained or supplemented: 

(a)     by course of performance, course of dealing or usage of trade (Section 55-1-303 NMSA 1978); and
