Where to find Milk Powder?
Is this something sold at the common market or do you need to go to a specialty store?

Other wise called dry milk or powdered milk. I'd look near the baking section of your grocery, along with the cans of evaporated and condensed milk. Most likely it will be the non-fat version. Asian and Latin groceries also carry Nido (Nestle) whole fat dry milk (also under the Klim label).
for quite a while Carnation, the largest manufacturer of powdered milk, stopped producing it. reading between the lines on their website some months ago, the new plant was WAY behind schedule, and they had to close the old plant. Once they get going again, powdered milk should be relatively common in most grocery stores. I can't find the section on the nestle/carnation website, maybe it is back in production now.
I found powdered milk in every grocery store within 10 miles during a marathon search for plain malted milk powder (eventually ordered online, if anyone else is looking). Some carried store brand, others had national brands.
As someone else said, check the baking aisle. After that, either the (hot) drink section.
