I have called Gerber. They said the contract with Manning has been finished. So they will not put stock in Manning in the future. But Ho Fa will sell the milk bag instead. However, they don't have enough stock in Gerber's warehouse as well. That's why you can't see many bags selling in the market.
I have complained that Ho Fa is not convenient to many ma ma because it's branches are not so many.
I am using Avent milk bags and bread clips. You can buy it at Pricenite, $12.9 for 24 clips.
It is basically the same as Avent clip, but cheap a lot and durable.
