New at Gamestop

Hello, I recently got a job at GameStop and I am really enjoying it but there’s something I definitely want to improve on. Does anyone have any tips for how to improve my selling ability? I want to improve so I can be a better worker. I also want to ensure that I am doing a good job so I can keep doing this as long as I can. It’s genuinely been one of the best jobs I’ve had so far.
