Being retired I do a lot of baby sitting. What my kids spend on day care, diapers, formula etc. is outrageous. Amazon sent out this link and it does look like it saves money. In addition, the convenience factor is huge. Working parents have NO time so having essentials delivered can be a major time saver.
Amazon offers new parents the easiest way to buy baby essentials and save with:
Free 2-Day Shipping on all diapers, wipes, and formula sold by Amazon
An additional 15% savings through Subscribe & Save, our auto-delivery program
Favorite brands like Pampers, Seventh Generation, Huggies, and Similac.
Here is the link to the site.
