For those of you ladies with a Walgreens nearby you might want to go check their clearance shelf/formula shelf. My Walgreens has the pre-made 6 pack of Enfamil Gentlease on clearance for $5.74 (does not expire until the end of 2014). If you have formula checks that's .74 per 6 pack! Although I breastfeed I picked up some for emergencies and to donate. There was also another brand name formula on clearance for about $15. I believe it was a full size Enfamil tin but I didn't really pay attention because the pre-made was such a good deal.
