Early access — Amazon used-offer alerts are not live yet. eBay used-listing search is available inside the app.

Stop Missing Used Deals on the Exact Items You Want

Checking Amazon for a specific used item is manual and tedious. You check, refresh, check again, and still miss the deal. UsedAlert will watch your items for you. Amazon alerts are not live yet; eBay used-listing search works today.

Build Your Watchlist Free

Three steps to set up your watchlist

Set it up once. Once Amazon alerts go live, we handle the watching and you handle the buying.

1

Add Items

Paste an Amazon product URL or type an ASIN. Full product links carry the name, which we fill in for you; otherwise name the item yourself so you recognise it later.

2

We Watch

Our system watches for used offers that match your condition preferences and optional price ceiling.

3

Get Alerts

You receive an email (and a push notification if you turned them on) with the condition, price, the seller's condition note, and a link to open the product on Amazon and check the used offers.

The gap nobody filled

I built UsedAlert for myself. My pool's sanitizer needs a replacement cell that costs well over a thousand dollars new. Last fall I bought one from Amazon Resale in Very Good condition for about a third of that. The catch: used offers on that part show up rarely and vanish fast, and the only way to catch one was to open the product page every day and look.

Amazon's own notifications cover new price drops on items in your cart or lists. They never tell you a used offer appeared, and they cannot be limited to a condition grade. Price trackers like CamelCamelCamel can alert on the lowest used price, but they cannot tell Like New from Acceptable, and they do not see every offer.

So if you are waiting for a specific item in Like New under a price you set, checking by hand was the only option. UsedAlert closes that gap. You tell it the item, the used conditions you would accept, and an optional max price. It emails you when a matching offer appears.

Common questions

Is UsedAlert free?
Yes. UsedAlert is free to use and does not require a credit card. We earn a small commission when purchases are made through our alert links as an Amazon Associate.
How often does UsedAlert check for used offers?
Once Amazon alerts launch, watched items are checked every few minutes. They are not live yet during early access. When a used offer appears that matches your condition preferences and optional price ceiling, we send an email alert (and a push notification if you enabled push in the app).
How is this different from Amazon's built-in price alerts?
Amazon's price-drop notifications cover the new price of items in your cart or lists. They do not tell you when a used offer appears, and they cannot be limited to a condition grade. UsedAlert was built specifically to alert on used offers by condition grade.
What can I use today during early access?
You can build your Amazon watchlist now so it is ready when alerts launch, search used and refurbished listings on eBay from the Search tab, and read our Used Picks guides on which products are worth buying used.
How is this different from CamelCamelCamel?
CamelCamelCamel tracks price history and can alert when the lowest third-party used price drops below a target. It does not know whether that offer is Like New or Acceptable, and by its own documentation it cannot see every third-party offer. UsedAlert watches for individual used offers that match the condition grades you accept, with an optional price ceiling per item.
Does UsedAlert work with Amazon outside the US?
UsedAlert watches amazon.com, the US marketplace. You can paste a link from another Amazon site and we will take the ASIN from it, but we watch that ASIN on amazon.com — and the same ASIN is occasionally a different product there, so open the amazon.com listing to confirm before saving. Alerts, prices, and purchase links are all amazon.com.
