Amazon offers a free Baby Welcome Box for those who sign up for a free Amazon Baby Registry and have Amazon Prime. This box includes a mix of samples and full-sized products for babies, valued at $35. To qualify, you need to complete a registry checklist and make a minimum purchase. 

The Welcome Gift is available to customers with active Amazon Prime accounts, who create a Baby Gift List, add 10 unique items from their Checklist and have more than $10 of purchases from their registry (by themselves or others).
