Help sellng candy at school

So my friend started selling candy and he was able to buy an iphone in a month. I want to do this to but the problem is my school has a "security check" where thay check your bags before coming in to school. I need to know how to sneek the candy in and where to buy the candy un bulks 30+ bars. I'm good in the how not to get caught.

The check is there because it's ILLEGAL to sell at school! Your nitwit friend has not been caught and or has BS'd you to think he earned enough to bey that phone

I used to hide them inside my best, hope this helps
