Plum District has an awesome deal for Diapers.com.  You can score a $40 Diapers.com gift certificate for only $20.   You can head over here to check it out.

Diapers.com offers free shipping when you spend $49 or more.

Here is the fine print:

• Vouchers may only be used on any items in the “Diapers” category (including Training, Overnight, Swim diapers)
• Limit one voucher per household
• Must redeem in single order
• Shipping and handling not included
• Offer may not be combined with any other offers, discounts, promotions or credits
• Vouchers redeemable after 9/24
• Expires 11/20/10

Note: If you are a new Diapers.com customer, you might be able to use coupon code: DIAPERSNEW to score 15% off as well.  I’m just not sure how the certificate and the discount code will work together.  They also have a program where you can earn 30% cash back on diapers that you can read about here.
