You're in control

Saving an item never notifies the seller and never makes an offer.

Help me negotiate is optional, inside the offer flow. It drafts a message for you to edit. It does not send that message, and it cannot confirm a deal.

A private budget stays private. It is not shown to the other parent.

If the price, item, quantity or pickup terms change, earlier approvals no longer count. Both parents approve the current terms.

You can withdraw an offer before you confirm. After a deal is reserved, either parent can cancel it.
