I'm not sure if you can use food share card online with ALDI. If you were to place a order, I'm sure that you'd be able to make a choice like you do in the store with your cards.
Truthfully I neverseeked a home delivery from Aldi but you can call to find out if they do have the apps such deliveries. If they do,I would use it also.
