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.

"On the Supreme Community website, when you look at each drop, they have a voting system — underneath each picture of an item, you can see if it has thumbs-up or thumbs-down ratings, like on Rotten Tomatoes," Christopher Young, a 21-year-old who says he makes as much as $300 per week flipping Supreme products, told Business Insider.

"That gives you a general idea of, 'Oh, this is something that people really like, or this is something people don't really like.'"

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.

"You have to go on in advance and figure out what section your item is going to be in — is it going to be in 'tops' or in 't-shirts?' Is it going to be in 'accessories' or in 'bags?'" Young said.

Morell said that he is usually on the computer, waiting, at least 30 minutes before everything goes on sale.

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.

"It's an interesting game," Young said.

"Sometimes you'll be really happy with it, and sometimes you'll be super disappointed."

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.

Several shoppers and bot sellers have said that if Supreme catches you using a bot, it can block your IP address and shipping address.

Supreme did not immediately return Business Insider's request for comment on that reported practice.

"I remember there was one jacket that I really wanted, so I clicked on it on the website at 11:00 a.m., and it was already sold out by the time the page loaded. Stuff like that happens all the time, and it's very obvious that it's bots," Young told Business Insider.

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.

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.

"The lowest amount I ever got was retail value on a sweater. I once sold a bag very quickly, and made twice the original value of it — the bag was $70, and I made $135," he 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.
