Lactose

Lactose. Milk Sugar. It's not an unusual thing. Phoenix. It's a big city. I need 2 POUNDS of lactose for the creme brulee stout. The local homebrew shops sell lactose, in 4 oz packages, for 2.50 a pack. I need 2 lbs. On line, lactose is suggested to add to kids' cereal, and other things. I cannot find it in AZ. I called 6 or 7 health food stores and organic grocery stores. No luck. 2 pounds of lactose is $3.49 from an online store. Oy. Pain in the butt.
