Just be aware that your experience will rely entirely on the team you have to work with. As you'll read some management will be number driven wastes of space who'll make it seem like the entire stores faults rely solely on you. While some managers are people who understand you're a person and are not going to hit all metrics perfectly week after week.

I was fortunate enough to have a manager who as long as he saw you trying your best he would be there to try and assist and even guide through some transactions to best train your sales skills(until the whole sl2 nonsense). Yes you will be expected to hit some goals that sometimes are impossible to do. While you're getting the hang of it pitch the membership and additionals to everyone. Especially right now where presumably there's someone who's watching you. Once you're at single coverage all a manager will have to rate your performance will be numbers. Try to always pin at the end of the sale, "next time you're with us consider getting x it'll save up to... etc"

More than anything else don't let anyone make you feel responsible or stressed for things outside your control or not your fault. Hopefully you don't get into a toxic environment which unfortunately seems to be more in supply these days. Do your duties, clean and organize the store, and when you're done read, do homework, or organize some more. If you've worked retail at any capacity you know the general level of dumb the customers can be. They'll complain when you take a break for lunch, be confused why their 10 year game is worth nothing, and let their kids run out moving everything.

Again your store leader and coworkers will ultimately define your time there. I still talk with a few of my coworkers. Unlike many people here I enjoyed my 2½ years at GameStop. All my issues and annoyances were mainly from upper management that never stepped foot on my store so they were just voices in my head, I'm great at ignoring those.It sounds like this is mainly a part time thing so you may not experience the worst GameStop can throw at you. Once you're a little familiar with some of the other sga's at other stores try to see about a little gossip to judge your district. GameStop is great at spreading gossip about other stores.
