Eugenie and her husband, Vladimir, executed a written contract with Rasputin Auction Co. to auction their furnishings. The six-page 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 Rasputin's commission. When a dispute arose between the parties, Eugenie and Vladimir sued Rasputin for breach of contract, asserting that, before they executed the contract, Rasputin made various oral representations that were inconsistent with the terms of their written agreement. Assuming that their written contract was valid, can Eugenie and Vladimir recover for breach of an oral contract?
