Want a free $35 Baby Welcome Box from Amazon? First, you need to be an Amazon Prime member. Second, you need an Amazon Baby Registry (free to sign up). Third, find something that costs $10 add it to the registry and buy it (doesn’t actually have to be a baby item). Wait until it ships, then go into your account and claim the baby box. Finally, during checkout make sure you’ve used the button to “Use $35 promotional credit.” Then the box is free.
