Check official channels first, always
Even for a sold-out show, official ticket providers sometimes release additional allocation, returns or previously held-back tickets close to the date — check the official seller before looking anywhere else. This is also the only way to be confident a last-minute ticket is genuine.
For theatre specifically, day seats and returns queues are a long-standing tradition at many West End venues, offering a small number of tickets at the box office on the day, usually at a reduced price — worth checking a show's official site for whether it operates a scheme like this.
Be wary of urgency pressure
Unofficial resale sites often use countdown timers and 'only X left' messaging to push a fast decision. That doesn't automatically mean a listing is fraudulent, but it's exactly the situation where you're least likely to stop and check the seller is legitimate — so slow down anyway, especially for high-value tickets.
If a price looks dramatically below what you'd expect for a popular event, that's more often a sign of a problem than a genuine bargain.
Where flexibility helps most
If you can be flexible on exactly which night, or whether you go to a similar show/artist instead of one specific sold-out date, you'll generally have a much easier and cheaper last-minute experience than chasing one specific sold-out performance.
