Aldi takes some getting used to.
They only take cash or debit cards for payment. If you want a cart, you need a quarter to use as the key. If you don't bring your own bags, theirs are 5 cents each.
Produce quality varies day to day, and can range from marginal to excellent, at the same store. Produce is not refrigerated, so I try to get there early.
They only sell their own house brand products. Some are great, some are loaded with all sorts of artificial crap. I read the ingredient lists carefully and note what meets my standards.
With a little patience, quality food can be had at prices 33 to 50 percent lower than anywhere else. I consider it a worthwhile trade off.
