Rimma Vaks Vs. Ryan Auction Company - Oral Contract

  Rimma Vaks and her husband, Steven Mangano, executed a written contract with Denise Ryan and Ryan Auction Co. to auction their furnishings. The sixpage contract provided a detailed summary of the parties' agreement. It addressed the items to be auctioned, how reserve prices would be determined, and the amount of Ryan's commission. When a dispute arose between the parties, Vaks and Mangano sued Ryan for breach of contract. Vaks and Mangano asserted that, before they executed the contract, Ryan had made various oral representations that were inconsistent with the terms of their written agreement. Assuming that their written contract was valid, can Vaks and Mangano recover for breach of an oral contract? Why or why not?
