The secret to Aldi & Lidl is that after a few visits you know what to buy and what not to buy. Sugar is sugar, milk is milk etc.
But I have also found a lot of stuff that is great and far cheaper for example Aldi free range eggs are absolutely delicious, the frozen battered Haddock is great too...
Aldi & Lidl, the best thing to have happened in retail in this country for years. The likes of Tesco and Sainsburys are crumbling and will soon have no choice but to severly reduce their prices and about time too they have ripped off the public for far to long.
