How Gradda works

Most marketplaces advertise a ticket price and add fees at the last screen. That's why the cheapest-looking site often isn't. Every number on Gradda is what you'd actually pay per ticket, fees included, so the comparison means something.

The gaps are not small. On the games we compare, a quarter of them differ by more than 25% between the cheapest and the dearest site for the same event.

We read the public listings on Ticketmaster, VividSeats, StubHub and GoTickets and record the cheapest available seat on each. We don't sell tickets and we don't hold inventory — when you buy, you buy on their site.

Every price carries the time we checked it. Resale moves fast, and a figure without a timestamp is a guess dressed up as a fact.

Checking a price costs us money, so we don't check every game on every site every day. Games close to kick-off and the ones we've marked as big get compared across all four. The rest show the sites we've checked, and say plainly which ones we haven't.

Creating an alert on a game moves it to the front of that queue: we go and check every marketplace for it straight away.

Tell us the game and what you're willing to pay, and we email you when a listing comes in under it — all-in, so the number in the email is the number you pay. Leave the price blank and we'll watch for any drop of 5% or more below today's.

One email when it matches. We don't send newsletters and we don't pass your address to the marketplaces — see the privacy policy.

If you click through and buy, the marketplace may pay us a commission. It never changes your price, and it never changes the order of the comparison — cheapest first, always. That's in the terms, so it's a commitment rather than a nice sentence.
