The “satisfaction guaranteed or your money back” guarantee is a promotional technique commonly used in distance selling, allowing the buyer to return a product and receive a refund if they are not satisfied. This offer aims to reduce consumer risk aversion, particularly for new products, by offering a trial period that can vary in length depending on the company, often between 7 and 30 days. Refund conditions may include proof of purchase and sometimes a brief explanation of the dissatisfaction. This guarantee constitutes a strong selling point, distinct from traditional legal guarantees.
