No one wants to run with the ball Reb, so I'll toss in two bob's worth.
I find them fair. No way do they make the margins the haters claim. Aldi have just opened and I've been there once and that limited experience says we can save 10% on some common items [block cheese] but others they simply don't stock. If you are taking a little extra time to read the labels and buy the healthy alternative you will stick to the big two. I was surprised how little shelf space Aldi put over to groceries. If they pick and choose what they stock, they can save on rent.
Colesworth is 2 km away, Aldi 15 km. These things matter.
