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 has two seasons: Fall/Winter and Spring/Summer. New products are released in events called "drops" every Thursday throughout the season, and they usually sell out within seconds online.

Before drops, people who flip Supreme typically do hours of online research to see what products will be coming out, what products people like or dislike, and what is predicted to have the highest resale value. One website fans use is Supreme Community, which leaks the details of product releases before they happen and allows users to vote on their favorite products.

Because of how quickly products sell out, people who flip Supreme products practice using the website to make sure they can buy the most-wanted items before they're gone.

Checking out can be a scramble — products can sell out even when they're already in your cart, so many people only buy one product a week to make sure they get something to sell. Even if you're buying just one product, you can turn a profit of as much as $300 a week throughout a season.

Part of why it's so hard to actually buy anything before it sells out is the use of automated bots. Some people who plan on reselling reportedly spend as much as $150 on automated bots that can be programmed to automatically buy products in certain colors or sizes in seconds.

Typically, small items like pins and stickers are under $30, while shirts, bags, and hats will cost between $30 and $100. Jackets, hoodies, and pants usually cost between $100 and $300, with a few outliers.

Within minutes of going on sale, the most popular products can end up on eBay for many times the original price. One of the most popular items from week one of the season — a Madonna t-shirt — cost $48 at Supreme, and within hours of the in-store drop, it was listed on eBay at a starting price of $250.

Another popular reselling website is Grailed. Within 45 minutes of Supreme's online launch, products like backpacks, t-shirts, and bags were listed on Grailed for more than twice the retail price.

Morell told Business Insider: "I set a budget for myself every week, which usually ranges from $300-$500. As soon as I get a shipping confirmation email, I immediately post the items I want to sell on Grailed. I usually receive a ton of offers within the day, and bargain with them as much as I can."

Results from flipping can be pretty hit or miss. "I got a lot for the Supreme Zippo last season. It retailed for $60, and I ended up selling it for $150. I remember being super shocked by that," Young said.

And profits aren't always guaranteed. "My biggest Supreme mistake was buying a Kayak for $480. Predicted resell was over $1,000. I went ahead and copped one, only for it to lose value immediately when it went on sale. I ended up selling it for $470 after fees and shipping," Morell said.

Though the sellers we spoke to typically make under $1,000 a month, some sellers are able to make much more than that from just one item. For example, a big-ticket item like the Supreme/Louis Vuitton Box Logo Tee — originally $495 — goes for well over $1,000 on eBay.
