Aldi has most foods stacked in display boxes instead of on shelves. If you're grabbing the last item from a display box, feel free to take the box and use it to put groceries in your car. (It's probably not the best solution if you walked or rode on two wheels.) Aldi likely won't have everything you need, but they have most things. As you go down the aisles, you'll notice they're pretty clearly laid out in a pattern. Pretend there are arrows on the floor like at IKEA to avoid going against the flow of shoppers.
