Curb Alert: What Reddit Says About Grabbing (and Flipping) Free Curbside Stuff
"Curb alert" is Reddit shorthand for the best free find there is: something good left on the curb for whoever grabs it first. On r/Dumpsterdiving and r/flea_market_flipping, curb alerts and "stooping" finds are a genre of their own — working electronics, gym equipment, solid-wood furniture, and tools that someone put out during a move. The lesson Reddit repeats: curb finds are a real income source if you can move fast and know what's actually worth grabbing.
Here's what those communities say about curb alerts — and how to work them well.
What Reddit says about curb finds
Move fast. On r/Dumpsterdiving, the recurring theme is that the best curb finds are gone within the hour. Move-out days, end-of-month, and college turnover are peak windows.
Some of the best free finds are curbside. Real examples people flip: a free radial-arm saw estimated around ~$300, a free squat rack with Rogue plates around ~$600, working refrigerators and ovens ~$200–350 each, ellipticals and treadmills ~$150+ — all things that regularly appear on curbs (estimates, not guarantees).
Etiquette matters. Reddit is firm on this: only take what's clearly marked free or on a public curb, don't block driveways, don't make a mess digging, and leave the spot cleaner than you found it. It keeps neighborhoods friendly to the next person.
Know the value before you stop. The most-upvoted curb-alert advice is also the simplest: don't haul a bulky item home on a hunch. Know roughly what it resells for first.
Turning curb alerts into a real feed
The hard part of curb finds is that they're scattered and fleeting — you can't refresh five apps all day. Freebox pulls the free curbside and giveaway listings near you into one feed, puts an estimated resale value and profit on each, ranks them by margin, and alerts you when a high-value one drops — so you're the fast one on the good curb alerts. It's an independent iPhone and web app, not affiliated with Reddit, and starts with a 3-day free trial, then $2.49/week or $39.99/year. The curb finds are free; Freebox does the valuing and the alerting.
