Aldi's is a popular German supermarket chain that is open on Christmas Eve, offering a wide range of products including groceries, household items, and seasonal items such as Christmas decorations and gifts. The store hours may vary by location, but most Aldi stores will be open on Christmas Eve for at least a few hours to accommodate last-minute shoppers. However, it's always a good idea to check your local store's hours in advance to avoid any surprises or disappointment.
