Welcome to Aurora Rout via here.
On the nights I can't get off to sleep properly I read. I am currently re-reading Mrs. Milburn's diary. She quoted some prices for August 1940 so I used the historic calculator to see how much they would be today!
Greengages 2d for 1 lb - now 49p
Other plums 1d for 1 lb - now 24p
Dozen Eggs 2s 6d - now £7.29p one month later £10.20p
Butter 1s 7d for 1 lb - now £4.62p
Milk 4d per pint - now 97p
Lemon 5d each - now £1.21p
Sweets 4s for 1lb - now £11.66p
Cox's Orange Pippin Apples 1s 3d for 1lb - now £3.64p
Blemheim Apples 11d for lb - now £2.67p
Brazil Nuts 1s 3d for 1lb - now £3.64p
Fur Coat £37 - now £2157.25p
She also mentions some prices from the First World War:
1 large chicken 22s 6d - now £69.71p
Evening Dress £18 18s - now £60.42p
Black Georgette £12 12s - now £40.28p
12 h.p. Rover Car £350 - now £21,687.64p
Despite rationing, just because a lot of things were rationed didn't mean you could afford them. Mrs Milburn was probably what would be referred to as middle class.
