These people make hundreds of dollars a month flipping products from a skater brand that teens are obsessed with. Here's how they do it.

Supreme, Gen Z's favorite skater brand, has become a source of income for some savvy shoppers.

Supreme was founded in 1994 by James Jebbia and has since grown from a skater-centric brand to a mainstream apparel brand with its own cult following. The brand ranked seventh among upper-income teens' favorite brands in a spring 2018 survey by Piper Jaffray, and in 2017, Supreme received a roughly $500 million cash infusion from The Carlyle Group, which valued the brand at $1 billion.

Last week, loyal fans snatched up copies of the New York Post that featured a wraparound Supreme ad on the cover. The papers, which typically costs $1.50, flew off the shelves. Copies of it are now listed on eBay for many times its normal listing price.

There's a huge market for reselling Supreme products because of the extremely high demand. Some fans are able to make hundreds of dollars a week by flipping products they're able to buy when they're released in product launches called "drops."

But because of how quickly products sell out, people who flip them have to prepare.

"During Supreme season, I'm constantly researching, buying, and selling - it usually doesn't stop until the season is over," 21-year-old Supreme fan Jake Morell told Business Insider.

Morell says he typically makes as much as $600 per month throughout a season, which includes one drop a week from August to December.
