When I used to go to the laundromat a couple years ago, regular size machines were $2.50 and the larger ones ranged from $4.50 to $10 for the really huge one. Dryers were like a quarter per 8 minutes. It may be a bit more now. The laundromat on Cleveland in the MD took cards but idk about that one in Lakeside unfortunately. ETA laundromats usually have change machines in my experience.
