Thanks to Rachel for this Frugal BabyTip!
Diaper Pail: We have 2 - one for poopies and one for wet. They are just Sterilite (like Rubbermaid) containers with snap-tite lids. We line them with "stuff" bags from the camping dept. of Wal-mart.
Baby Wipes: We bought 3 dozen blue washcloths at Sams Club, and dip them in a water/castille soap mixture that sits in a wipe warmer. It lasts a few days, then I refill it.
