See how visitors reserve a wish on a shared Bestboy list — no account needed — so nobody accidentally buys the same gift twice for the same person.
When you open someone's shared wishlist link, you can reserve any wish that isn't already claimed — no account needed.
The list owner never sees who reserved a wish, only that it's reserved — the surprise is safe. If the list has donation-enabled wishes, you'll see a Donate button on those instead of (or alongside) Reserve.
No — anyone with the shared list link can reserve a wish without creating an account.
Yes — a wish you've reserved shows a Reserved — undo option to you, so you can release it again if your plans change.
No — the owner only sees that a wish is reserved, never who reserved it, so the surprise stays safe.
