I was there today and saw it in the refrigerator section with the regular yogurt. If it's not there check in the speciality section.
My Aldi grocer says that they just started carrying it two weeks ago. It's not a special buy. But it's still expensive at $0.89 per single serving cup. Hopefully they'll soon add the tubs. But for now we get to choose from strawberry, blueberry and plain.
Yay! This makes me happy. :))
