It depends on what you have learned this year. Use the skills you have learned as capital to talk to the store manager. You have to figure out what important questions you will ask you if you are the store manager, and how to answer his questions perfectly. If you want to get a raise, you must show him your value. If you are the same as a year ago, I suggest you don't talk about it yet, study hard and make yourself valuable, so that your salary will not be low wherever you go.
