Generic Formula Vs. Brand name formula?

if the label has the exact same ingredients as yours does then it's the same. for instance my son can only have nutramigen and sam's club has a formula that has the exact same ingredients as nutramigen, the labels are identical. so that would work for us. however since i feed 90% and formula feed 10% he's still on the nutramigen that is open, and we have 4 more cans, but trust me if we have to buy more we wil buy the generic, i mean we pay $27 a can for name brand or $32 for a can 3x the size of the name brand that is the same thing. so it's the same thing, you pay for the advertisement on the name brand stuff. that's all.
