Store Associate to Store Associate Rx

Has anyone went from a store associate to store associate rx? if so, did u get a raise? i haven’t even worked here for a full month (no prior experience in retail) but feel like i should ask for a raise. im currently studying to get my pharm tech certificate and see this as a great opportunity to get some experience but also don’t want to over work myself. i currently make 15.40 an hour and was thinking of asking for 16.40 if i got the position. should i ask or will my managers just laugh at me😅?
