Save a Marketplace listing, get alerted when the ask drops vs local comps, and message first. Try Saved on a free Day Pass (no card).
To catch a Facebook Marketplace price drop, save the listing so it is re-checked, compared to local asking-price comps, and alerted when the ask falls or hits your target. Refreshing the same ad by hand is how you miss the hour the seller finally blinks.
Try Saved on a no-card Day Pass. Five saved listings, 24 hours. Pass facts: Facebook Marketplace Day Pass.
Most buyers only hunt brand-new posts. The other half of deal craft is the car you already liked that sat too high on Tuesday. When that seller cuts, the first clear message often wins, because they just admitted the old ask was not working.
A price drop closes more deals because it is a seller signal, not just a cheaper sticker. The listing is already live. Photos exist. The seller has waited. A cut means they want the thread to move.
A new post can be a steal, a typo, or bait. You still have to triage it. A saved listing you already vetted is different: you decided the truck, the miles, and the title path were worth a number. The only open question was price. You are not discovering the car at the cut. You are arriving with a number you can defend.
Facebook does not publish a reliable "notify me when this ask changes" product with comps attached. Timing varies by account and day. There is no published SLA. If you care about one listing, you have to track it on purpose.
Saved is your team's own list of individual Facebook Marketplace listings that Crawlbench re-checks for price movement. It is not a search, and it is not the list of listings a search finds.
Keep the two tools in their lanes:
You add a row in two ways: paste a Marketplace listing URL on Saved, or choose Save on a listing card or in the listing drawer. Saved listings show a chip on the feed so you do not add the same car twice.
The list is shared across the team. Owner, Admin, and Member can add, retarget, stop, and bulk-act. Caps follow the owning account's plan, pooled across every team that owner bills for.
Add only listings you would buy at a number, not every interesting thumbnail. Saved rows count against your plan's cap, so spend them on listings you would buy.
Start with this shortlist:
Do not save miracle prices. A $4,000 Tacoma next to a $19,000 band is usually salvage, a parts car, or a scam. Treat those with the same underpriced checklist you use on new alerts: verify first, cash never until the car and title are real.
Paste the full Facebook Marketplace listing link. If the listing already passed one of your searches, use Save on the card so the row is tagged from a search. Pasted rows show added by link. Same team, same checks, different origin.
The movement track answers four questions on one rail: what they asked when you added it, what they ask today, where your target sits, and where the local cohort median sits. If you cannot read those four points, you will message on hope.
Read it in this order:
The rail also keeps a short trail of later observations, so a seller who zigzags $18,400 to $17,900 to $18,200 does not look like a clean cut. "I can do $17,900 today" is a different message when you know the median is $18,400 and they already came down $900. You are answering the number they just printed.
Comps on a watched listing tell you whether today's ask is under, near, or over the local median, and when the discount is so deep you should verify instead of celebrate. A cut toward a fair band is a deal signal. A cut into fantasy is often junk.
The same vocabulary shows up on listing cards and Market Snapshot:
Asking-price comps are the public list prices of similar vehicles, not verified solds. Use them to decide whether to message. Use a guide or your own sold math later if you need a finance or flip floor. The longer argument lives in asking-price comps vs KBB.
Low sample means the window does not have enough priced listings for a confident median. Treat that number as directional. Wait, widen the year band in your head, or lean on the movement versus this seller instead of versus the market.
Set a target below today's ask, at the number that makes you move, and leave it blank if any drop is enough. Target hit means the current ask is at or below that number.
A useful target is the all-in number after transport, expected reconditioning, fees, and flip margin. Example: a 2016 Toyota Tacoma asks $19,800. Local clean asks for that year cluster around $18,400 to $20,500. You will pay $17,900 delivered. Set the target at $17,900. Do not set $19,200 just to get a ping.
Rules that keep your list honest:
If the seller raises the ask, the target does not move with them. That is the point. Your number stays your number.
Use the four lanes as a queue, not as decoration. Target hit and Moved down are where you spend attention. Raised and Flat are where you stop burning evenings.
Stop a row when the thesis is dead or a teammate already has it. Ended watches collect under No longer watching and stop costing a check.
A watch ends when the listing sells, leaves Marketplace, you stop it, or the 60-day window runs out. From day 14 the card shows day N of 60. Selling or leaving Marketplace sends one notice. Re-adding the same listing starts a fresh watch.
A price-cut alert is a channel ping when a listing you care about lowers its ask. It is not a new-listing alert, and it is not Crawlbench messaging the seller for you.
Two things put a listing in scope:
Searches re-price listings as they come back through your filters. Crawlbench checks busy cities every 10 minutes on Starter, every 5 on Growth, every 2 on Pro and every minute on Scale, as pricing shows on 18 October 2026. Saved re-checks every saved listing on purpose, so it is the sure way to catch a cut on a listing you care about. A listing that passed a search and is also saved still only alerts once.
Unlike new-listing alerts, price-cut alerts are not limited to listings posted in the last three hours. An eight-day-old Tacoma that finally drops is still in play. The first-hour rule still applies to fresh steals. Saved covers the slower half of the tape.
Alerts go out on your usual channels (email, Telegram, Slack, Discord) to every membership with that channel on. Turning a channel off, or turning a search off, still wins. Crawlbench does not send the Facebook message. You do, from your own Marketplace thread.
A saved listing is re-checked by Crawlbench on its own, not on Facebook's notification mood. When a check sees the seller cut the ask, the price-cut alert goes out on your channels, wherever the listing is.
You can also run Check now on a row or a bulk selection when you are about to drive or send a second message.
Saved caps by plan: Day Pass 5, Starter 10, Growth 20, Pro 40, Scale 150, pooled across the teams you own. If you are at the cap, stop a flat row before you add a better one. Bulk actions cover stop, target, check now, and CSV export.
Copy this when you want the feature to make you money instead of making you a collector of saved cards.
You run a 2015–2018 Toyota Tacoma search in one metro. A clean 2016 asks $19,800. Photos are real. Title language is normal. Local asking-price comps sit near $18,400 median, typical range roughly $17,900–$20,500. You will not pay $19,800. You will pay $17,900.
The cut gives you timing. The median gives you posture. The target keeps you from talking yourself into $18,600 because you are tired of waiting. Sellers who just cut are answering messages. Buyers who only chase new posts are still refreshing Newest. You show up in the gap with a specific number.
Saved works best once you have a number. Hold off when you have not decided one, when you would be using it as a bookmark pile, or when the listing is a new-listing problem a search should filter first.
Skip it when:
A search with tight filters still does the volume job. Saved does the patience job. Use both. Do not make Saved a second unread inbox.
The close is still you, in Messenger, with a clean offer. Saved only does the part humans are bad at: remembering 20 asks, noticing a $600 cut, and knowing whether that cut is under the local tape.
If you want searches and Saved on one plan, start on vehicle monitoring or compare caps on pricing. The click-by-click setup is in the Saved guide. The value is not another feed. It is arriving at the seller's cut with a number you already chose.
