"Cheapo" supermarkets (Aldi/Lidl). 75% of the price for 50% of the quality and 25% of the customer service
10 years ago when they were genuinely LOADS cheaper than the big supermarkets it was maybe a fair trade off, but the truth these days is, they're not that much cheaper and the quality on most items is shocking, especially fresh meat/veg.
Although I do like Lidl yoghurts

(I also agree on tinfoil by the way - cheap tinfoil is pointless)
