Prime Big Deal Days 2026
What Happens If You Sign Up for Prime During Prime Big Deal Days?
You get the remaining window, not the whole event. Prime Big Deal Days runs 48 hours from 12:01 a.m. PDT on October 6, 2026, and a Prime membership started in the middle of it takes effect for the hours still ahead. Nothing is locked out, and nothing already gone comes back.

What you still get
- Member exclusive pricing for the rest of the run.
- Today's Big Deals drops, which Amazon refreshes three times a day, so later drops are yours.
- Invite only deal requests, if the products you want still have requests open.
- Everything outside the event, for as long as the membership runs afterwards.
That last line is the part people forget. The membership keeps working after the sand runs out.
What you have already missed
The opening hours. Limited-quantity deals that sold out during them are finished, and the earliest early deals window has passed. If a specific item was the whole reason, check it is still live before you assume joining will reach it.
Two days is long enough to still work and short enough that waiting has a price.
The steps, in order
The part nobody says out loud. Signing up during the event is not different from signing up before it. The steps are the same, and the clock is shorter.
- Confirm the trial length shown on your sign-up screen before you accept it.
- Check eligibility first. If a trial is not offered to you, that is an Amazon decision.
- Shop the live drops once access is active, rather than browsing categories you were never going to buy from.
- Set your own reminder for the day before your billing date.
Buy it if something on your list is still live and the remaining hours cover it.
Skip it if the item that brought you here already sold out. Joining for a deal that is gone is just joining.
