Yep, I've been generally happy with Aldi quality. For instance their diced tomatos in a can have lots of diced tomato in the can, not a few tomato bits floating in juice like other cheap brands can sometimes be. Same with their canned corn and kidney beans. Their pesto is also good.

We generally go to Aldi once every 2-3 months and stock up on pantry staples (i.e. we buy 36 cans of tomatoes!). It really saves on the grocery bills for us.
