There is nothing unique about their shopping carts. We have one Costco branch and one local supermarket that do the same thing. It does cut down on carts all over the lot. Years ago Adi in Germany split up into Aldi Nord (North) and Aldi Sud(South). They also split up the foreign countries where Aldi had stores. The US went to Aldi Sud. Trader Joes is owned by Aldi Nord.Aldi's is a discount grocery chain. They are owned by a German company. The US part is based in the Chicago area. A lot of their products are from Europe. FWIW, you put a quarter in a slot on the buggy and it released a chain. Put the chain back into the buggy in front and get your quarter back. Saves salary for employees to go out and fetch buggies. I used to do that at Lowe's- not fun in the rain or winter.
George, I got four for $99 and free shipping. See the last part of post #3. I have a dead Ryobi battery sitting on the shelf.
