How exactly do you make money from ecommerce? Do you have to be the one who sources, ships and manages products online? Does age stop you from being successful online?

Alex Philip is one of a new breed of young entrepreneurs determined not to let their age hold them back.
The 14-year-old Londoner is currently turning over $30,000 a month and making $5,000 in profits, by sourcing products on Alibaba and selling them through Shopify, using drop shipping to simplify the process, and is on track to make $250,000 ($60,000 profit) this year alone.
