Pros
For part-time flexible hours and if you're a student you can get tuition reimbursement (If you work +13 hours and payed for your tuition). Also, good bounce as you work more hours. And once you stay long enough you can get health insurance and vacation days paid (you can get these benefits has a full time, but if you're and in high school and going to college after this would be better to keep flexible hours and later on get the perks),
Cons
At first, they give you a lot of information and even as you work with the company, there will be new things to learn. Bad thing about that is that store managers can get mad because other managers haven't explained to the clerks. So, it can be frustrating, this job is also a lot of talking so if your shy then that would be a problem.
