Pros: Some positions pay more than minimum wage
Cons: It's not worth it
Unless you are able to function with the speed, accuracy, commitment, lifespan, strength, and emotional coldness of a robot, you're better off finding a job elsewhere. CVS demands far more than what they compensate you for, and enough is never enough.
The work in and of itself is not difficult, but is very repetitive, and requires endless amounts of patience dealing with the public. The management hierarchy is a system that only works well if you have an incredible manager...which is hard to find. There is room to grow in the company, but not enough incentive to make it worth it.
