Sue Thompson received a home "cold-canvas" sales call from a representative of the Enlightened Encyclopedia Company. The salesperson, after a rather aggressive presentation, convinced Sue to order a $1,200 Deluxe Encyclopedia set for her two children. Sue was impressed with the quality of the books, but shortly after signing the contract, she realized that she could not really afford to make the required monthly payments.

What rights, if any, does Sue have in this situation?
