Dried buttermilk powder [Cooking]

2014 Jul 22
I'm looking for a good quality buttermilk powder, preferably SACO brand. I just used the last bit and have looked for it at Superstore, Loblaws and Food Basics. Not one of those stores carry it. Note that I do NOT want to buy it from a bulk food store. Does anyone know where I might find this? I can't remember where I bought my last batch but since I couldn't find it at any of the aforementioned stores, I have a sneaky feeling that I may have purchased it in the States. TIA.

I bought some awhile back at the Herb & Spice on Wellington, but I can't remember if it was branded or repackaged bulk.
