Imperfect substitute

An imperfect substitute refers to a product or service that can be used in place of another, but does not perfectly replicate or match the original item. This means that while the substitute might serve a similar purpose, there are differences in quality, price, features, or other attributes that make it a less ideal replacement. Consumers may choose to use an imperfect substitute when the original item is unavailable or too expensive, but they may not be completely satisfied with the substitute's performance or characteristics.
