The best place, by far, to get your clothes dry cleaned. It's cheap, and may affect your alignment. Simply drop off the clothes you want to be cleaned, and they'll think you're donating them. They dry clean them and then put them up for sale. So just come back the next day, buy your clothes back, and they'll be dry cleaned. You will have saved a lot of cash, considering it's almost free.
Proceed with caution. This is evil, but perhaps angelic by my standards.
