Aldi has gone more Whole Foods then Trader Joe's, while still being everyone on price. No more artificial ingredients or colorings. Everything is organic and natural. Prices are still rock bottom, but quality is improved.
The stores have been updated and upgraded so they are not dull, but brighter and colorful. Selection, while still limited, has expanded beyond the 150+/- from a few years ago when cashiers had to memorize the prices of each item, to 1500 since they installed bar code readers.
I generally shop Aldi for the staples, and fill in from Mariano's ingredients they don't carry.
Hawkmoon, I would suggest maybe going back and checking out the "new" Aldi, and a lot has changed in the past 5 years with them.
