The average UK weekly consumption of baked beans in tomato sauce per person has declined from a peak of 95gm in 2008, to 79gms in 2019/20. A standard can is 415gms, of which 51% is beans; 211gms. The average price of that Heinz can around British supermarkets is £1.20, except in Tesco which are not re-stocking.

The principle source of dry navy beans for Heinz is the USA, where the biggest farms are in Minnesota and North Dakota. Latest wholesale prices are $0.44 to $0.48 a pound, a record, and equivalent to around 18p for the 211gms necessary for each standard can. Then you've got to put it into containers, drive across the USA and ship to Wigan, where Heinz operate the largest baked bean processing factory in the world, re-hydrate, add the other ingredients, process and ship out again. 

There's not much spare in US supplies, with little in storage, and farms reducing their planting because of the wet spring.
