I know there was a thread like this a couple of weeks ago but blimey I was impressed yesterday.
I usually shop in Sainsburys, for 3 of us is about £90- £100 (excluding weekends food, because we always eat out, but includes stuff for lunch in the week).
Bought the same variety of stuff in Aldi yesterday, cost £50.
DD curled her lip at the own brand stuff, but DP was delighted, as bought a load of German stuff (which he loves as he lived in Germany for years).
Can't believe how cheap it was, and took so little time as the shop is about one tenth the size of Sainsburys.
It was great - I had never been there before and I was very pleased indeed.
