I was struck by this weekly round up of deals at Baby Cheapskate:

Formula, Milk and Food
Cans of Enfamil and Similac are $22.99 at CVS. Earth’s Best organic formula is cheap again at Amazon. Under $22 for the big can, shipped. Two-packs of Gerber 1st foods are .89 at Target. Kroger has 6 oz. jars of Gerber baby food for .67.

So right now, Earth’s Best is $22 for 25.7 ounces and Enfamil and Similac are $23 for 23.2 ounces or whatever random size those new tubs are. If you are thinking about making the switch to organic formula, now is the time!
