If you're a subscriber to Parents magazine, be sure to look on page 96 of your brand new August issue. You should find a one-time-use Amazon coupon code to save 20% on a box of diapers from Amazon.com. The best part? It can be stacked with this 30% off deal + your $1.50 Amazon Pampers coupon and you'll get free 2-day shipping!
If you have a code you're not going to use, please leave it in a comment so another reader can use it!
