No. A show is live only. Nothing is kept afterwards and there is nothing to catch up on.
Said plainly because the alternative is you hunting for something that does not exist.
What you can still see
The show's own page, which lists what went up, what sold and what did not.
Anything unsold, usually back as an ordinary listing or in the store's next show. Worth asking about — "did the green one sell?" gets an answer.
The store's next show and its date, with a reminder you can set. That is the useful thing on that page.
Why it works this way
Partly because the point of the format is that it is happening now — an auction you watch afterwards is a video of other people buying things.
And partly because recording live video is a separate piece of machinery that is not switched on. That is the honest reason for the second half of the answer.
How not to miss one
Follow the store. The only reliable method. You are told when they go live and when they schedule.
Set a reminder on a scheduled show. Coming up is ordered by start time and anyone can set one.
Check your notifications are actually arriving. A reminder you never see is the commonest reason people miss shows they meant to attend. Notifications, explained
If you missed an item you wanted
Ask the store. If it did not sell, it is still theirs. If it did, they may have another or be able to find one. Can I ask a seller to find me something?
Look at their listings. Plenty of stock never goes into a show.
If you cannot attend shows at all
Reasonable — they are at fixed times and you have a life.
Buy at fixed prices instead. A large amount of what sells here is ordinary listings with no clock. Buy now, explained
Leave a pre-bid where a store allows it, and let the auction happen without you. You are told the outcome either way. How bidding works
Neither needs you to be anywhere at eight o'clock.
