The allure of the luxury window display pulls shoppers into stores from Madison Avenue to Fifth Avenue to the Meatpacking District. Manhattan has everything for the well-heeled, but the city is also home to people who don’t buy anything.

Ingrid Wang is part of a viral trend called “Buy Nothing.” The 27-year-old does not buy anything new.

“It was my New Year’s resolution last year to buy nothing new as much as possible,” said Wang.

She relies on her neighborhood "Buy Nothing" Facebook group and thrift shops for her wants and needs.

“You’ll be really surprised at what you can save from the landfill,” said Wang.

And so far she says she’s been successful, finding items like a container which she uses for cat food, a kettle, and a speaker, all for free.

“I was looking online, scouring 'Buy Nothing,' and finally someone posted this [speaker] when they were moving out, so I commented right away, and was able to pick it up, walk across the street and grab it,” she said.

"Buy Nothing" Facebook groups are becoming increasingly popular in the city and around the world. It started more than a decade ago with two friends in Washington state, and now, they say there are groups in 44 countries.

Kara Perez, author of the book "Green Money," which offers a roadmap to redefine personal finance through environmental sustainability, says their rise signals a change in consumer spending habits

“It teaches people you don’t have to spend money to get what you need. You can ask other people, you can build community, you can borrow, you can trade, you can swap, it kinda refreshes our brain of, hey, there's other ways that I can get what I need, without having to go into credit card debt, without having to spend all my cash, without having to stress myself out financially,’” Perez said.

Queens mother of two Carrie Brown Albanese calls her Long Island City "Buy Nothing" page the group that keeps on giving.  

“We got this amazing Bugaboo stroller from it, which is an incredible gift someone gifted to us. My husband got a jogging stroller, and he’s a huge runner, so that was an amazing gift for him, and he’s taken both of our children out,” said Albanese, the page’s administrator, along with her husband, Chris.

While she is not exclusively living a Buy Nothing lifestyle, she recently set a goal to buy fewer new items for her family of four.

“Being intentional about just purchasing fewer things, and asking myself, 'Is this a want or is this a need?'” Albanese said.

It's not just about the environment: She estimates she's saved thousands of dollars.

“It’s been incredible. I think, for us, the biggest savings has been in children’s clothing, so children’s clothing you wear it, the kids grow out of it sometimes before they even get a few wears in,” she said.

Wang admits she had a penchant for browsing and buying, and still continues to browse, but even buying nothing can be addictive. 

“I always feel like I’ve kinda won the lottery if I comment first on an item and am able to grab it,” Wang said.
