How soon is too soon to gather stuff?

When did you first start gathering major items (car seat/crib/etc)? I’m only 15w so this stuff is totally off my radar, but a friend just posted an infant car seat for free on Facebook and it’s pretty tempting to ask for it, despite very intentionally not telling anyone we’re pregnant yet... What would you do?
