We usually purchase Luvs brand diapers, since they work very well AND they are one of the cheapest. When you sign up for Amazon Mom (free), you will receive 15% off your baby orders. In addition to the first 15% off, they will give you ANOTHER 15% off if you sign up for "Subscribe and Save", when you order.
For example, Luvs Ultra Leakguards Diapers, Size 1, 300 Count are normally around $44, but with the first 15% off the price comes down to about $38. ANOTHER 15% off from subscribe and save brings the total to around $32!!
$32 is way better than $44!!
