On the morning of this year’s sale on Oct. 25, the line to get in snaked around the hallway on the 7th floor of his Industry City, Brooklyn building. By 9:30 a.m., half an hour before the sale began, more than 300 shoppers had arrived, looking for a deal.

Approximately 1,100 available items ranged from small tchotchkes — vases, decorative balls and light fixtures, priced at a few dollars each — to bigger items, including couches, dining room tables and a vintage wooden bookcase. Products were pulled from the roughly 150,000 items that resided in Mr. Saft’s 24,000-square-foot warehouse and office, four floors below. A $1,500 Lappi sofa was now $700. Eames chairs, originally $250 each, were $75. A skirted table bought from a designer for $900 was $250.

Mr. Saft, 48, estimated that 300 people showed up last year, purchasing some 200 items. This year, he gauged, attendance quadrupled. “People trust my eye and feel like they’ll find something interesting,” he said. “And everyone loves a bargain.”

Nana Eyeson-Akiwowo, 48, an independent consultant for luxury brands, drove in with a friend from Englewood, N.J., and secured a prime spot in line by 8:15 a.m.

“When Jason posted on Instagram that he was doing a Crazy Eddie-style sale, I knew I was coming,” she said. “I love the way he designs.”

Ms. Eyeson-Akiwowo was clear about what she was looking for. “Furniture for our master bedroom. And yes, I have furniture already, but I feel like I’m going to find something great,” she said. “In the words of Denzel Washington, ‘I’m leaving here with something.’”

As the line grew, the crowd remained calm and unfazed. People stood and strategized with one another; others sat on the floor in groups, drinking coffee, scrolling on their phones and chatting. Some came with their dogs, some with babies.

The mood quickly changed when the doors opened promptly at 10 a.m. and the previously placid group angled to get inside.

A quick scan of the room revealed piles of pillows, rolls of rugs wrapped in unopened plastic, light fixtures, tables, night stands, and plants. Artwork ranged from $10 to $30, while slabs of marble were free for the taking. Yes, free.

The 35-plus couches and about 300 chairs included weathered, outdoor furniture as well as more upscale pieces “that weren’t working aesthetically or were overbought,” Mr. Saft said.

Dressed in a denim shirt, khaki pants and brown suede shoes, Mr. Saft circulated like a politician running for office. He greeted everyone warmly and enthusiastically, humbled by the turnout and by those who wanted to meet him.

“I worked three jobs and put myself through a working man’s college. I was told at a young age that I wouldn’t grow up to be much,” he said. “I was always in trouble, but I always wanted to accomplish something.”

Through his 20s and 30s, Mr. Saft drank heavily and did drugs, and as he puts it, “kind of gave up on life,” he said. “When I turned 40, I got sober. I feel very fortunate. I never imagined I would accomplish something. To see so many people, and how excited they are, gives me a sense of pride I’ve never had before. It’s profound.”

Deciding what to part with, Mr. Saft said, was possible in part because of Airtable, the organizational tool, which he uses to log every item his company acquires and track how often an item is used.

The list took six weeks to amass, longer than it takes Mr. Saft to stage a home.

“Physical staging can take two days,” he said, “If we’re doing cosmetic work, like painting, wallpapering or refinishing floors, and depending upon the size of the home, that can take three days to two weeks.”

Currently, Mr. Saft is staging 50 projects, from a 650-square-foot one bedroom to the 10,000-square-foot, five-story, Pfizer Mansion in Clinton Hill, Brooklyn. Mr. Saft’s fees start at $22,000 for a one bedroom and can rocket up from there. He recently charged $175,000 to stage a 45-foot wide double townhouse, priced at $75 million.

Sarah Kruse, 40, an interior designer and founder of the design company, Storie, was a third-time attendee and found a couch for a client’s office for $1,200, which she bet was originally $3,000.

Mark Boyett, 60, an audiobook producer for Bookmark Audio, and his husband, Paresh Patel, came to replace their couch.

“Ours is a bit dog-eared,” said Mr. Patel, 56, a city government operations director. “He wants to stick with neutral tones. I want our color to pop. The goal is to remain married after this sample sale. So hopefully we’ll come to a consensus.”

Rob Friedman, 38, a freelance filmmaker and editor, probed for items he could sell on Facebook Marketplace. He arrived 10 minutes after the sale began to find “a lot of things had been sold,” he said, as he stood unperturbed by the 30-minute wait to pay. His bags were filled with decorative $1 hanging balls, “which I could sell for $20 a piece,” he said.

While serious shoppers came armed with tape measures and photos of their floor plans, others guesstimated. Some marinated. Ms. Eyeson-Akiwowo decided quickly.

She beamed as she sat cross-legged on a beautiful velvety silver couch, priced at $450. Her pose reinforced the fact that this was now hers.

When Ms. Eyeson-Akiwowo felt a stickiness on the side, she waved away the imperfection. “I’m going to get a cushion cleaner and we’ll be fine,” she said.

Shoppers carried out what they could: large plants and small chairs, with pillows and vases balanced on top, rugs slung over shoulders, picture frames held under arms. Mr. Saft’s moving team handled larger pieces with professional moving blankets, clear packing tape and dollies.

The frenzy subsided by 11 a.m. Indecisive shoppers sat on couches they were considering; others took additional laps to see if they missed anything.

By noon it was slim pickings. Prices had been marked down by an additional 25 to 30 percent. And by 1 p.m., only castoffs remained.

For many shoppers, this was a chance to score discounted home goods. For A. Piper McCoy, the sale was a lifeline.

“We had a house fire in February and lost everything,” said Ms. McCoy, 39, who lives in West Orange, N.J. and came with her fiancé.

Ms. McCoy, the vice president of global communications at the independent ticketing platform, DICE, was up at 6 a.m. for this event. “This sale is allowing us to create new memories. I’m coming in trusting this because of Jason’s background,” she said.

Ms. McCoy scored an orange acrylic end table, two green chairs in velvet “and knickknacks that we can add throughout the house to bring back some personality and charm,” she said.

That was part of her purchasing goal. Mr. Saft had a goal as well.

“I don’t want a single thing left,” he said. “I wanted to give people that feeling and rush of someone who loves a sale. Then I want to give what’s left to charity.”
