Generally, it can be said that for every product or service, there is a potential buyer. However, it's important to note that the demand for a particular product or service can vary depending on factors such as consumer preferences, market conditions, pricing, and marketing efforts. While there may be a potential buyer for most products or services, the level of demand and the number of buyers can vary significantly. Additionally, certain niche or specialized products/services may have a more limited pool of potential buyers.
