Do you buy it from the web or do you buy it in the store?
We used to buy from Amazon.com and then switched to Diapers.com. Now we buy from Target Store.
I loved Pampers Sensitive when she was little. Now we use Pampers Pull-up with the Dora pictures.
My recommendation for moms-to-be is not to stock up on too many Size N diapers. Sometimes it is okay to start with Size 1. Babies grow fast.
