Only one joiner is needed to complete your Team-Up. Here is how it works when multiple people have your link:
First to checkout wins the pairing The first person to complete checkout is paired with you and your deal closes instantly.
What happens to everyone else? Your invite link remains active after your deal completes. Anyone who taps it afterward can still access the Team-Up price, but their purchase will start a new, separate Team-Up deal rather than joining yours.
Public feed Your open deal is also visible in the public Join feed, so any Blidz shopper may join before any of your directly invited friends do. You only need one joiner regardless of where they come from.
