I do 1 load of laundry a day (approx) and line dry outside. Do you think given how much water and electricity bills are, that using the biggest machines at the launderette is cheaper. I think my launderette charges £4 and I can fit about 2 loads in.
I can walk to the launderette; its 5 mins away although admittedly hard work with a bag full of washing.

As least you know what’s been in your washing machine! Just imagine your smalls going in after some scabby old farts!!
