Walmart offers the Dr. Brown's BPA-Free Natural Flow Bottle Newborn Feeding Set, model no. 240-P6, for $13.06. Opt for Site-to-Store pickup to avoid the $4.97 shipping charge. (Amazon offers it for the same price for Prime members.) That's the lowest price we could find by $6. It includes three 8-oz. bottles with level one nipples, two 4-oz. bottles with level one nipples, two level two nipples, two storage/travel caps, and three cleaning brushes.
