It’s always good to know what the grocery store sector is worried about. By the way, Trader Joes is part of the same company.

‘ALDI has accidentally reinvented pantry stocking in America by subversively eliminating the variable brand and the shopper marketing that goes along with it. They have also eliminated the variable of price, for there are no price comparisons in a store with only one offering in every category. They have made it radically simpler, cognitively, to execute a shopping trip. No thinking about brands, BOGOs, deals, price comps, coupons, sudden endcap promotions or in-aisle shopper marketing. The trip is also super-fast, because the stores are only about 18-20,000 square feet.’
