The cost involve in picking up the sample is minimum and the cost of data collection is also generally low. For example, the investigator wants to study the demand for the types of soft drinks. The interviewer can go to some soft drinks shop and can interview shopkeepers who happens to come to that particular shop and ask them questions regarding their choice for soft drinks.
