I’m totally not surprised that you've never heard of Aldi. It’s a German discount grocery chain and it’s essentially the Jan Brady of supermarkets, overshadowed by the more famous Marcia, Marcia, Marcia. Or in this case, Trader Joe's. Yeah, that.
Quick history: Karl and Theo Albrecht, two brothers, founded the stores in Europe in the 1940s and when the sibs, now-deceased, parted ways a couple decades later, the markets did likewise. Aldi’s been in the U.S. since the '70s, with nearly 1,500 stores in 30-plus states today. Plans are afoot to boost that number by 33% by the end of 2018. A new one arrives in Selden, Long Island, in the fall, raising the number there to six.
