Lidl's fuit and veg is much cheaper, but the range is limited and if you go in the evening, a lot of it might run out. Their tomatoes on the vine are a fraction of what Sainsbury's/Morrisson's charge. And it's not that limited - you can still get things like magoes, avocados, shallots....
Things I get in Lidl: canned tomotoes/chopped tomatoes, cheap coke for ds/dh, cheap crisps for ds/dh (£1.49 I think for a mulipack of 24 bags), multi vitmain fruit jucie for ds, apple juice, multi-packs of mini apple and multi-vitamin juices for ds, tomatoes on the vine, spinach leaves, grapes, bananas, oranges, apples, cucumber, avocadoes, dry cure bacon, milk, Gold (look-a-like), butter, cream, 75% plain chocolate bars, pasta, olive oil, basmati rice, frozen chips, frozen chicken nuggets (for our "slob in front of the TV Friday night suppers"), strawberry ice cream, muilti packs of wee fromage frais for ds, mozarella, parmesan, emmenthalle, Cava (a perfectly respectable bubbly for ony £3,49 - also for a our "slob in front of the TV Friday night suppers", cans of salted almonds., flour, sugar, rich tea biscuits, jaffa cakes (nicer than the "real" ones, crackers, rye bread, brown bread for toasting, fabric conditioner.
I'll occasionally get mince or other meat - but will ususally get that either at Sainsbury's or a local butcher
Mum and Dad say their muesli is also excellent (I don't like muesli)
Things I get in Sainsbury's - either because Lidl doesn't stock it or becaseu I prefer the quality:
fresh herbs (although I can get parsley/chives/basil plants at Lidl), more "esoteric" veg eg celeriac or red cabbage (althugh if it is not a "Sainbury's week" I will go to the local greengrocer), almonds, brazil nuts, cornflakes, shredded wheat, baking pwder, caster sugar, branded washing powder, dried herbs/spices (although Lidl does do some), loo roll, unsalted butter, free range eggs (only 'cos I like them large and Lidl only does them medium), free range chicken, ready cooked Indian or Chinese meal (our alternate ""slob in front of the TV Friday night suppers"), dite ginger beer, fruit shoots....
... but we don't get all of the above every week!
