As far as i know it’s just that Trader Joe’s is owned by Aldi Nord, while Aldi US is owned by Aldi Süd. Aldi Nord and Aldi Nord are two separate chains.
Aargh.Aldi Nord and Aldi Süd are separate.
Billionaire brothers ran each chain. The one brother lived so quietly on his estate apparently he died and the rest of the world didn’t know about it for months.
I used to avoid Aldi and I’m somewhat addicted to regular supermarkets. But Aldi has a lot of really good products at excellent prices and their checkout is super fast.
