I do Aldi, Sainsbury's and ice land.
Aldi I get cupboard stuff, cleaning, baking stuff, chocolate, biscuits, yoghurt.
Cooked meats, beer, wine, baby stuff all fine. Not keen on their squash, prefer Sainsbury's. Loo till, kitchen roll all fine.
Toiletries fine but limited range.
Crisps, chocolate, sweets, crackers are good
Tinned stuff all good. Dairy stuff is fine, Pure juice
I don't get frozen foods as I prefer Iceland.
I don't like their chicken as it doesn't look great quality.
The 5% mince products are fine, as it's the beef roasting joints.
The veg is hit and miss imo. I only ever get a couple of days worth as I find it goes off easily.
I don't get any other raw meat the as I prefer a butcher and we don't eat it.
I spend about 60-70 per week there. £20 Iceland for frozen foods.
I then spend about £40-50 in Sainsbury's as I can't get everything in Aldi, or don't want to - see above re fruit, veg, chicken.
However I'm not a good example of frugal shopping
