Yes we have big machines to accommodate comforters and large loads. The big washes are$4. All other washers are $2. The dryers are $0.50 for 10 minutes to start and 5 minutes for $0.25. A typical load of clothes costs about $1-$1.50 to dry.
A load of laundry is around $5 to $6 dollars, depending on wash cycle. The dryers are 50 cents for 8 minutes, and 25 cents for every 4 minutes after. I do not see a problem with washing a comforter. They also offer a cleaning service as well, however I do not know the price they charge for each type of laundry.
