Free tool — live eBay data, no signup
Paste your eBay listing URL and see the lowest competitor on that exact item — plus what Undercut would price it at to win the sale, without ever dropping below your floor.
Paste a full listing link (the one with /itm/…) for an exact, like-for-like check. A plain product search also works, but matches loosely — see the note on those results.
Every search above is a snapshot: the lowest price on eBay changes constantly as competitors undercut each other, run sales, or sell out. If you sell anything with competition, the listing that wins this morning can be overpriced by tonight. Sellers either babysit their listings, or they automate it.
Undercut runs this exact lookup for every listing you have, around the clock, and reprices you a penny under the lowest competitor — but never below the per-item price floor you set. Work out that floor with the fee calculator, connect your store in one click, and stop checking prices by hand.
Undercut watches the lowest competitor on every listing and reprices you to win — floor-protected. Start free, no card.

How does the eBay price checker work?
It queries live eBay listings for your search term, sorted by price, and shows the lowest current price, how many competing listings exist, and the cheapest individual listings. It is the same competitor-low lookup the Undercut repricer runs for its users automatically.
Why does the lowest price matter so much on eBay?
For commodity items, eBay buyers sort by price + shipping, so the cheapest credible listing wins most of the sales. If you are priced above the lowest competitor you lose velocity; if you chase them blindly you lose margin. The answer is repricing with a floor: beat the competitor only while it is still profitable.
How often do eBay prices change?
In competitive categories the lowest price can change many times a day as sellers undercut each other or sell out. That is why checking manually does not scale past a handful of listings — automated repricers re-check around the clock.
What should I do if the lowest price is below my cost?
Do not follow it down. Compute your break-even floor (cost + shipping + fees) and hold there — sellers chasing a below-cost competitor lose money on every sale. Undercut enforces that floor automatically: it undercuts when profitable and stops dead at your minimum.
