InfaSoy Baby Milk Formula

It is almost impossible to find the Aspen Infasoy infant milk formula from stores. Some stores have advised that it has been discontinued. Why were stores not made aware of this in time so they could warn us in time. You can't just change the Baby's formula. I'm in such a panic because I am almost out of my "stash" as I bought as many as I could when i heard they have been discontinued. Please advise if this Formula has really been discontinued? and are there any alternatives?
