38.3 Sales. On June 28, a salesperson for Renowned Books called on the Gonchars at their home. After a very persuasive sales pitch by the agent, the Gonchars agreed in writing to purchase a twenty-volume set of historical encyclopedias from Renowned Books for a total of $299. A down payment of $35 was required, with the remainder of the cost to be paid in monthly payments over a one-year period. Two days later, the Gonchars, having second thoughts, contacted the book company and stated that they had decided to rescind the contract. Renowned Books said this would be impossible. Has Renowned Books violated any consumer law by not allowing the Gonchars to rescind their contract? Explain.
