You need a quarter for a cart, you get it back when you return the cart.
Pay for bags, bring your own or sometimes they have boxes available.
Cheap produce, it would be good to know the days they get produce delivery - some locations the produce gets past prime quickly.
Look online for the special buys for each week they also have recipes/meal planners based on the products they carry.
They have a double your money back guarantee. ... bring it back, they will replace it
and give your money back.
It's a good store to "fill in" for daily staples like produce and dairy.
Checkout .. the lines have been very fast for me

Put your stuff on the belt, they quickly scan and plop it in the previous person's cart. Use debit/check card or cash only (EBT accepted too) , slide your cart up to them for next person. Take your goodies and bag it yourself or push it out to your car. Bring the cart back to the entrance, snap the bike lock looking thing into the cart and out pops a quarter. We now keep a spare quarter in the cup holder of our car all the time.
Ya have to know your prices and what type of shopper you are... if you have a Super
Walmart nearby, the prices may be similar or slightly less. If you coupon a lot, you might sneer at the prices because you know you can get it cheaper with sale and doubles... If you are the no hassle approach, just give me a good price and let me out of here kind of shopper -- you will love Aldi's!
So far I've liked their products,
