  Terms with respect to which the confirmatory memoranda of the parties agree or which are otherwise set forth in 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:

      1.  By course of performance, course of dealing or usage of trade (NRS 104.1303); and
