Did the three$-$day cooling off period solve the consumer problem it intended to solve?

Yes it did after the enactment of the FTC Door$-$to$-$Door Sales Rule

Yes it did because for certain contracts the consumer had the right to cancel within a three$-$day cooling off period

No$,$ it did not because different states adopted the rules using different language and at different dates

Though it helps and is a step in the right direction, it did not completely solve the problem because there is no universal three$-$day cooling$-$off period
