The latest supermarket chain to offer organics is none other than discount grocer Aldi.

Aldi began testing some organic produce and products in its stores in September and has expanded to include stores in the South and Midwest.

Aldi organics still cost more than their conventional products but generally cost less than organics at other supermarkets. In Minneapolis, for example, Aldi products cost up to 40 percent less than other area stores.

Organics are growing in popularity, despite a Stanford study finding organics were not significantly more healthy than conventional products.

Aldi will test the organic products for a least six months.
