From now through the end of March, I get double credit for referring people to diapers.com, and new customers get their standard $10 discount for using a referral code on a qualifying order. The order has to be a minimum $49 (which doesn't have to be all diapers, they have wipes, lotions, formula, baby food, baby gear like strollers and carseats, etc.), but with an order of that size you also get free shipping. They accept mailed in manufacturers coupons and have a price match guarantee. My code is LA.M8408.
