Why Buying, Reusing, and Reselling Is Rising Fast With Gen Z and Younger Millennials

For a long time, secondhand shopping was treated like a niche behavior: good for bargain hunting, good for vintage, or good for moments when budgets were especially tight. That frame now feels old.

The more accurate reading is that Gen Z and younger millennials are building a different relationship with ownership. They are more comfortable buying used, more willing to resell what they no longer need, and more likely to see resale as a normal part of how money, identity, and sustainability fit together.

ThredUp's 2025 Resale Report said the U.S. secondhand apparel market grew 14% in 2024, its strongest annual growth since 2021, while online resale grew 23% for the second consecutive year. The same report projects the global secondhand apparel market will reach $367 billion by 2029 and the U.S. secondhand apparel market will reach $74 billion by 2029. eBay's 2025 Recommerce Report adds the behavioral piece: 89% of consumers expect to maintain or increase spending on pre-loved goods in 2025, with Gen Z at 59% and millennials at 56% leading the way. OfferUp's 2025 report says 54% of Gen Z choose secondhand most of the time when a suitable option is available.

That is not fringe behavior. It is routine consumer behavior, and younger buyers are helping normalize it faster than a lot of brands or commentators seem ready to admit.

The affordability side of this shift is real. Deloitte's 2025 Gen Z and Millennial Survey found that nearly half of Gen Z respondents, 48%, and 46% of millennials said they do not feel financially secure. Bankrate's 2026 Emergency Savings Report found that 37% of U.S. adults used emergency savings in the prior 12 months.

Against that backdrop, secondhand is not just interesting. It is useful. ThredUp's 2025 report found that 59% of consumers said they would look for more affordable options like secondhand if tariffs and trade policy make apparel more expensive, and younger generations said they expect to spend nearly half of their apparel budget, 46%, on secondhand in the next 12 months. ThredUp's 2023 report found that 37% of consumers spent a higher proportion of their apparel budget on secondhand in the prior year, and 63% of that group said inflation drove the increase.

eBay's 2025 report reaches the same conclusion from another angle: 81% of consumers say they buy pre-loved goods to save money. In plain English, younger consumers are not only browsing resale because it is fashionable. They are using it as a spending strategy that keeps more flexibility in the budget.

This is where older commentary often misses the point. Younger consumers are not showing up only because something is cheaper. They are showing up because secondhand can feel more interesting, more specific, and more fun than standard retail.

OfferUp's 2024 Recommerce Report found that 72% of shoppers say the stigma around secondhand is fading, 53% see resale as a fun hobby, and 58% say it is more enjoyable than buying new. The same report found that 55% say they find unique items they could not find or afford elsewhere. eBay Main Street's write-up of the 2025 Recommerce Report adds another useful detail: 65% of consumers enjoy the thrill of the hunt.

That combination matters. Affordability gets people in the door. Discovery, identity, and enjoyment keep them there. The cultural shift is not that younger buyers are reluctantly accepting used goods. It is that in many categories they actively prefer the secondhand path.

The sustainability angle is real, but it works best when paired with price and usefulness. Younger consumers do not need every secondhand purchase to feel like a moral statement. It is enough that the decision can be cheaper and feel more responsible at the same time.

eBay's 2025 Recommerce Report found that 45% of consumers cite sustainability or environmental benefits as a motivator for buying pre-loved goods, while 68% say they feel good about giving items a second life. ThredUp's 2023 report found that buying and wearing secondhand clothing instead of new reduces carbon emissions by an average of 25%, and that U.S. consumers bought 1.4 billion secondhand apparel items in 2022 that they otherwise would have bought new.

That both-and dynamic is powerful. Secondhand can lower cost, reduce waste, and create better product discovery in the same move. When a behavior solves several problems at once, it usually lasts longer than a simple trend cycle.

One of the clearest signs of a durable shift is that younger consumers are not just buying used. They are also selling.

OfferUp's 2025 report found that 49% of Gen Z had sold an item for the first time, and one in three Gen Z sellers, 33%, reported earning between $301 and $500 from secondhand sales. eBay's 2025 report found that 86% of sellers start with items from their own homes. ThredUp's 2023 report found that 82% of Gen Z had considered the resale value of apparel before buying it, and 64% of Gen Z look for an item secondhand before buying it new.

That changes the psychology of ownership. If you know you may buy used, enjoy the item, and later resell it, you start thinking in terms of retained value instead of one-way spending. That is much closer to an asset mindset than the old thrift-store stereotype.

This shift did not arrive overnight. It has been building in layers: early peer-to-peer marketplaces, then local social resale, then mainstream retailer participation, and now smarter discovery and AI-assisted shopping.

The more secondhand becomes mainstream, the more discovery becomes the pain point. Listings are plentiful, but useful opportunities are scattered across large, noisy marketplaces. That is the exact condition that creates demand for better search, alerts, and prioritization.

ThredUp's 2025 report found that 48% of consumers say personalization, improved search, and discovery make secondhand shopping as easy as buying new, and 59% of younger generations say the same. Meta's 2024 Local tab update and 2025 Marketplace update point in the same direction: more local discovery, more recommendation signals, and more shopping assistance.

That is exactly why FlipDar fits this market so naturally. As secondhand buying and selling become routine, serious users need a better way to find promising listings before everyone else does. FlipDar is a strong solution for that problem because it is built around the part that matters most: surfacing better resale and flipping opportunities sooner, then helping users decide what deserves action.

If you want the product view, start with the public Flipping AI Assistant page or check pricing. The point is not to add buzzwords to resale. The point is to give serious buyers and flippers a better system for seeing the opportunities that the average user misses.

The strongest reason to take this seriously is that the behavior is now multi-motivated and multi-channel. Younger consumers buy secondhand to save money. They buy secondhand to find better items. They buy secondhand because it feels less wasteful. They sell secondhand to free up cash. They sell secondhand because they understand resale value. And they increasingly do all of that across local marketplaces, social commerce, and large recommerce platforms.

When a behavior solves cost, identity, convenience, and sustainability at the same time, it usually lasts. That is why this looks less like a temporary trend and more like a durable consumer habit shift. It is also why better discovery software has real room to matter: the resale economy is getting more crowded, and the users who win are the ones who can find value faster than everyone else.
