When I first went to aldi it was all boxes on the floor and no prices, and I was in awe of the checkout staff, who knew the prices of everything in store in their heads, and so quick through the checkout. It always, well back in the nineties, seemed a store for the less well off, which included me and my partner then, this is just a personal observation....but now the car park of ours is full of big expensive cars waiting to park.
It does seem to be a store that recognises a 'trend' in an instant, and responds quickly with its own products. Usually very good and competitively priced.
I heard too about the meat, being as good, if not better than Marks and Sparks. However, I do support my local butcher.
As I have now to walk to my aldi, about fifteen minutes away, and carry all stuff back, I don't go as often as I ought as my local morrisons is two minutes away.
