Aldi is informing customers that a planned change will be rolled out in its stores starting from 21 May, according to reports from UK outlets. The updates say the change is being implemented as part of Aldi’s store-by-store rollout, meaning not every location may switch over at the same time. One outlet notes that the change is already starting to appear in some stores this week, while another reports that Aldi is telling customers to expect the rollout “from May 21” across all stores. The articles do not indicate a specific national date for every store to complete the change, only that the timeline begins on 21 May and that the transition is underway in some locations immediately ahead of that date. Overall, the coverage agrees that Aldi has issued a customer-facing notification and that the modification takes effect from 21 May, with early implementation in certain stores during the current week.
