basically it is cheaper than other methods so it is preferred over other methods.
Less expensive
Purposive sampling can allow the researcher to make generalizations about results. Purposive sampling also provides the researcher with many different sampling techniques.
Reduced Cost, Processing Power, Improved Network Technology, Scalability, Availability
there are 3 clusters of PECs these are the Achievement Cluster, Planning Cluster and the Power Cluster

A group of galaxies is called a galaxy cluster or galaxy group.
Advantages of cluster sampling include that it's inexpensive, fast, and simple. A disadvantage is that it is known to have a high sampling error.
What is the difference between quota sampling and cluster sampling
It can be but it is not simple random sampling.
Advantages of multistage sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
What I believe you are referring to is cluster sampling or cluster. In cluster sampling, the population is divided into clusters and all population members in the cluster are sampled.
Multistage sampling is a form of cluster sampling where instead of using the entire cluster, random samples from each cluster are used. This is typically used when doing opinion polls or surveys.
simple random, stratified sampling, cluster sampling
Simple Random Sample Stratified Random Sampling Cluster Sampling Systematic Sampling Convenience Sampling
There are many such methods: cluster sampling, stratified random sampling, simple random sampling.Their usefulness depends on the circumstances.
Answer is Quota sampling. Its one of the method of non-probability sampling.
advantages: reduce bias easy of sampling disadvantages: sampling error time consuming
