Cred air o bob deg a glywi, a thi a gei rywfaint bach o wir (hen ddihareb Gymraeg) Believe one tenth of what you hear, and you will get some little truth (old Welsh proverb)
In our supermarket one cooked chicken is £4.49 but if you buy two it is £7.00. It seems an unfair system for people who are living alone or only can eat one chicken at a time. As they are cooked it isn't as if you can buy it to freeze.
Cheap chickens is good for the consumer but I wonder how it affects how the chickens are reared.
My sister lives alone and buys a large tin of beans just for her because of the stupid price difference - in many ways she ends up wasting more food that way too if she doesn't manage to eat the 'other' half of the tin of beans in time.
There are many examples of how single people are penalised and it does encourage food waste which is something that we are told that we must cut down on.
It's usually cheaper to buy bigger tins of food and simply decant them into polythene lidded containers in the fridge if the contents can't be eaten at once. Baked beans & tomatoes for example will keep quite safely for several days like this if you don't want to eat them two days on the run.
The problem is that often she doesn't want to eat the rest so quickly - the beans tend to be an emergency quick fix meal. It's not a problem at the moment as she is off beans altogether after opening one tin to find it infested with maggots.
Really my point is that generally supermarket prices are unfair to people who live alone - the beans just came up as an example.
On the topic Large Can Beans / Small Can Beans, it is the same with all canned products. There is a certain minimum cost of the canning process which is more or less the same regardless of the size of can. - Unfair?
