I took the plunge and ordered from diapers.com. I was weary...but my order was shipped for free...and was here the day after I ordered. You can even send in your coupons for wipes, diapers and formula and they'll put them on your account for use for future orders.
Just wanted to let you know about my positive experience.
(Plus if you decided to try it out...if you use me as a referral you get $10 off your first order...and I get $1 off my future order. When you get to the shopping cart screen use my referral code: MJR826)
Re: Diapers.com
The fact that they deliver so quickly and take coupons was HUGE for me...
Here's the link that tells you how to send in your coupons...
