According to federal law, customers are entitled to a _____ "cooling off" period once the contract is signed.

Under federal law, specifically the Cooling-Off Rule enforced by the Federal Trade Commission (FTC), customers are entitled to a three-day "cooling off" period after signing certain types of contracts, such as those for door-to-door sales or other solicitations made away from the seller's normal place of business. This rule allows consumers to reconsider their purchase decision and provides them with the opportunity to cancel the contract within this timeframe without facing repercussions, which is designed to protect consumers from high-pressure sales tactics that may lead to hasty decisions. This understanding is crucial for anyone involved in sales or contract law, ensuring they are aware of consumer rights and the provisions that are in place to foster fair sales practices.
