Anyone who can worry about the life that the animals that make the value meat ranges have led, obviously still has the money to have ethics. I have had to abandon mine. Value meats, value eggs, value flipping everything here. Waitrose essentials is the best quality of all the 'cheap' ranges, but slightly dearer than the rest.
Asda smartprice? Not worth bothering with IMO. Everything I have tried from that range is minging. Tesco value isn't much better, though the butter is fine to cook with, and I always have to buy half as much chicken again as I would elsewhere due to the water content in the value chicken. Sainsbury's basics are the next best after Waitrose Essentials.
I don't have a Morrisons in my whole town, so I have no idea about that, don't have a Lidl's either. We have two Aldi's, but one of them is an hour and 15 minutes away on two buses, and the other is an hour away on one bus. I was actually thinking of popping there (ha!) next week, but it will basically take up my entire day, because I have to allow for an hour there and an hour back, time to shop in a shop I've never been in, and time to put the shopping away before I get on another bus to get the dc from school.
I used to have ethics, and only eat free-range and organic - but when you only have £100 a week to buy food, cleaning products and nappies for a family of 5, which is just £20 a week per person, for breakfast, lunch and dinner, that goes by the wayside in the face of having to EAT.
