Do not even mention the bachelors. Even say you went to school but it "wasn't for you" if they ask. The overqualified thing is real.
That is the perfect thing to say, that's exactly what they want to hear and will give you a great chance of landing the job.
Never under any circumstances put down any qualifications further than school, not even college, only list retail jobs and don't list too many.
You need to look like someone with no ambition that is likely to listen to everything they tell you to do.
Why on earth would they want people with ambition or good qualifications, that will only cause them problems in future and putting you amongst current staff could end up affecting them, the last thing they want is someone encouraging the staff to follow their dreams.
In your case it probably won't hurt you since you're applying for part time stuff on top of your main career. I would still remove it, leave the bachelor's in, and simplify your work experience so it mostly only stresses communication and customer handling skills. You'll just get more calls.
Do not do this, even if it's only for a part time position. Part timers are already more likely to move on and find new employment, employing someone that is over qualified and part time is suicide for retail and can poison other employees.
Take off any higher qualifications past school, full stop. Never mention any kind of ambition and just list experience with customers and working in retail.
