Which of the following is considered an illegal sign for retailers?

The phrase "No Returns Accepted" is considered an illegal sign for retailers because it can violate consumer rights and protections that are established by law. Many jurisdictions require retailers to allow returns or exchanges, especially if goods are faulty or not as described. This phrase may mislead consumers into thinking they have no recourse if the purchased product is defective or unsatisfactory, which contradicts consumer protection legislation that is designed to ensure fair trading practices.

In contrast, phrases like "All Sales Final" and "30-Day Return Policy" can still be used legally because they convey specific policies that are understood and accepted in certain contexts. "All Sales Final" indicates that the buyer has no right to a refund or exchange regardless of the circumstances, which is legal as long as it's clearly communicated. A "30-Day Return Policy" clearly states the terms under which returns can be made, adhering to legal standards if the retailer follows through on their policy. Similarly, a "Money Back Guarantee" is a positive assurance for consumers, generally fostering trust and satisfaction with the purchase experience, as it usually involves conditions that comply with legal requirements.
