Better buy more than one

So I put the value a little down because I bought one bottle and it cost me $8 then found out if you buy a 3 pack it's only $14. That's a free bottle I was disappointed of course. The bottle it's self is great though. It helped so my newborn did not burp as much. It even comes with a brush to clean the air flow piece. The only thing I wish they would change is the nipple shape. Since I breast feed I love the bottles with the nipple to be shaped more like an actual nipple. I can tell my baby notices the difference because when I give her this bottle she hesitates at first unlike her other bottle which has the natural nipple shape.
