The biggest problem with petco vs a local shop is that petco only hires part time employees. You cannot make any money working with them unless you are a manager and get full time. Do the people at walmart care, no. They get paid crap, work too hard and have no benefits at petco. They really dont give a crap about there employees.
They could have hired me but no full time... they want kids to work for them.
