How to know if a curb-alert street has already been picked over before you drive there

Our guide to spotting a genuinely high-value curb find helps you judge an item once you're looking at it. This is the step before that — deciding whether it's even worth the drive, since a curb alert post doesn't mean the items are still there by the time you see it.

Check the post timestamp first

A curb alert posted six hours ago in a busy area has a real chance of being picked clean already, especially for anything genuinely valuable. A post from the last 30–60 minutes is a much safer bet. This single number — how long ago it was posted — is the fastest filter before you commit to driving anywhere.

Read the comments before you leave

Comments like "still there?" with a reply of "yep, just grabbed the lamp but the rest is still out" tell you exactly what's left without needing to drive over. A thread with several "is this gone?" questions and no poster response is a yellow flag — either the poster's not actively monitoring it (so you genuinely don't know), or it's already been claimed and nobody's updated the post.

Look at what the photos actually show

A curb alert with a photo showing one item is usually accurate to what's there. A photo showing "everything must go" piles of multiple item types is riskier — the specific piece you want might already be gone even if the general pile photo is recent, since posters rarely update photos as individual items get taken.

Cross-reference with active discussion elsewhere

Some areas have active subreddits specifically for tracking curb alerts where people post real-time updates on what's still available at a given spot — worth a quick check if your area has one, since it can save you a wasted trip on something already gone.

High-traffic areas move faster than quiet ones

A curb alert on a busy street in a dense neighborhood gets picked over much faster than one on a quiet residential street with less foot and car traffic — factor the location itself into how urgently you need to respond, not just the posting time.

When you genuinely can't tell, message before you drive

A quick "is this still out there?" message to the poster, sent right before you'd leave, is the most reliable way to avoid a wasted trip — most posters will respond quickly if they're still near their phone, and it costs you nothing but a text.

The bottom line

Check how long ago it was posted, read the comments for real-time updates, and don't over-trust a "pile" photo for a specific item. When timing is genuinely unclear, a quick message before you leave beats guessing.
