Flora hall went to Rent A Center in Milwaukee and signed an agreement to make monthly payments of $77.96 for 19 months in exchange for Rent A Center allowing her to have a Rent A Center washer and dryer in her home. In addition, the agreement required Hall to pay tax and liability waiver fees on the washer and dryer. The total amount she would pay under the agreement was $1643.15. The agreement provided that Hall would return the washer and dryer at the end of the 19 months or she was at that time paid $161.91 and own the washer and dryer as her own. Is this a sales contract? Is this a consumer lease? At the time Hall leased her washer and dryer she could have purchased a set for $600. What do you think about the agreement? Is it unconscionable? What if any other consumer laws apply. Must this contract be in writing? (Rent A Center v. Hall 510 N.W.2d 789)
