I'm a couponer, so I know that I can get diapers a little cheaper if I hit the drugstore sales and coupon properly, but as dedicated a couponer as I am, the sales are not worth the cutthroat battles I've watched between moms rushing to get those sale diapers when CVS opens on Sunday mornings. It's worse than Black Friday, and I'm just not scrappy enough. I'd probably lose an eyelid.
Anyway, for $5-$6 more a month, they're delivered to my door right when I need them--and using Luvs, a $25 order lasts me a month (sometimes a little more).
