speaking of stocking up on diapers, etc. I buy ALL of my diapers on Amazon.com. If you sign up for their Amazon mom's program you get a free subscription to their Prime program (free 2 day shipping on everything you order). If you sign up for the Subscribe & Save on the diapers (or whatever else you want) you get a great discount. You can always order more if you need some in the meantime, but you set it up to deliver one box a month, for example. I can't remember the last time I bought diapers at the store.
Also, no tax.
Re: PSA: Amazon.com Moms program
I do this as well! I sign up for the subscription and then cancel it after I get the order. I always get 30% off with free shipping! One time I had 20% off discount codes from Parents magazine, too, and I ended up getting 200 diapers for $7 shipped!
hmmm what if you're already a prime member? I payed for my membership (like, a year ago)! that blows that I could have gotten it for free!
::edit:: I just joined and it said it would refund my unused months of prime, so that's cool!
I do the same!
