We don’t anymore to be honest, we hardly, if ever get anyone wanting them. People on a limited budget will just go to the sheds and pick up the cheapest washer they can get 😥
I like to keep one or two to offer customers when I condemn their existing elderly machine. These are usually in the £70 to £100 range depending on condition etc. I also get asked for cheap machines by people who furnish flats for factory workers shipped in for short contracts from places like Portugal. These people tend to wreck the machines so they are given tatty appliances and I might supply a job lot of 4 machines for £200. This is worth my while as I also charge for the repairs they inevitably soon need (I don’t guarantee them).
