Is this a good value for formula?

We buy the stuff at sam's club also and it is just fine. They wouldn't sell it if it weren't. We were giving out daughter the Enfamil reduced lactose and stared buying the members mark that says compare to....I looked at the back of both cans and they have the same amount ov everything. We've been using the member's mark brand for 3 months now and not had a single problem. It is so much cheaper than the other.
