The best prices for diapers seem to be on Amazon. Pampers Baby Dry Size 3, 222 ct is on sale with Amazon Moms and Subscribe & Save for $29.73 shipped, when you clip the $1.00 Pampers Coupon (should be below the product – void in NY). (be sure to change the count 222 for the best deal – the 144 count is also a good price, but not quite as cheap)
Not sure where to find the coupons on Amazon, read this post here.
