I got a 10% discount code for an online site that sells diapers and related products. I just ordered my diaper covers from there. It is www.bananapeelsdiapers.com and the discount code is "greenfest".
Also, I have a 20% off code for a great maternity store here that sells online. They also have some baby stuff and diaper bags. The website is www.nest-maternity.com. The code is "FF201". Haven't tried it online myself though.
Mama to my veggie girl (1/09) and my sweet rainbow baby (9/12).
