I remember Aldi from when I was a kid and I feel like the quality wasn't as good back then... maybe it was just being a kid and wanting name brand snacks.
I miss Winco in California...
In Illinois I was on Wal-Mart only partly for convenience of 24 hours, but when my work schedule normalized, I started checking out Aldi. I'm a convert, I love Aldi and tell everyone. It's definitely been trial and error like someone upthread said, but I feel like the more we shop there, the more we get at Aldi instead of having to make a different trip to Wal-Mart.
The only things we have to get at Wal-Mart now are Almond Milk (haven't seen it at our Aldi, but sometimes I think things are hiding) and coffee. We tried their brand, but get whichever is cheaper of folgers/maxwell at WM or the even closer store Shop N Save.
CSA has ended for us so I'm not sure what that will mean for produce shopping... we are the last 2 workers to still get our shares so we've still been working for veggies a couple of weeks after the paid shares are over. Then again we will most likely be moving in a month or so... oh no, we'll have to learn a new grocery store layout!
