Make extra cash as a teenager

This is most easiest way to become a small entrepreneur in school and this is how I did it.
I brought 60 freddo bars for £7 and then sold them to my friends for 25p per one. I was so busy with selling them, I had to buy 120 freddo bars per week just to keep up with demand, which means I made £16 per week every week also after selling freddo bars I then asked my mates would they buy lucozade bottles of me , the answer was 'yes' so I went and brought 50 bottles for £25. I sold them all for £1 each and made £25 profit plus the £16 profit and made me £41 profit per week.
Now that's good business for just selling in school ;) plz like and share ;)
