I shop at Aldi often. They moved into my Ohio area in the mid-1980s. Most products were OK. I mostly used them for Girl Scout snacks and camping food when the troop went on overnight camps. Eight year old girls will eat anything after a day outside.
When we moved to MA in 2000, there were no Aldis in the area. They arrived here 5-7 years after we did. I was amazed at the improvement in quality! Most everything I have bought these days is as good as most national brands. And if it's a tad less, the price difference can still make the Aldi choice fine depending on what the item is and how it's going to be used. And if you don't like what you bought, you can take it back to Aldi. They will give you your money back, plus let you pick out a replacement - either a second chance at the same item or a completely different item of equal or lesser value. Two examples: we like their corn chips. One time the bags I bought were greasy and heavily salted. That's not normal. When I returned them, I replaced them with two bags of perfectly fine chips. The second time was for a bag of snack cookies that didn't look like they were sweetened with an artificial sweetener. I couldn't get them past my taste buds. When I took them back, I picked something different as the replacement.
In my opinion, Aldi is a safe place to check for a decent store brand. You're never out your money if you buy something yucky while you look for tasty food. That's if they're close enough. I drive 17 miles to our Aldi every 4-6 weeks, but if they were closer I would include them in my weekly options.
