fyi: two loads of laundry can be dried at once, for $1
but three loads... will not be dried.
three will take two cycles, so you might as well wait until you've got four.

so... to summarize.

one load: two dollars (wash, dry)
two loads: three dollars (wash, wash, dry)
three loads: five dollars (wash, wash, wash, dry, dry)
four loads: six dollars (wash, wash, wash, wash, dry, dry)

do 'em by twos, folks.
not hard to figure out, but i'd never tried drying three at once before tonight (:
though... hm, this stuff is mostly dry... perhaps tolerable.
