I feel ya! Although I work a bit more than that, it's sooooo expensive to wash your clothes if you don't own a washer or dryer.
We bought a washer dryer set about 2 years ago and I figured it up that the washer and dryer paid for themselves after I went through TWO laundry soap bottles. Well worth it! Our laundromat was EXPENSIVE $5 wash and dry per load. Our water bill is only $20 a month and it's an energy star so I'm sure it doesn't cost much to run it. Thank god for living in a small town! I love our city bill, the highest it's ever been was $40!
