So, for the sake of making things simple, what is (approx) total cost of doing one load of laundry? (meaning no special settings, just your average load of laundry with t-shirts, jeans, socks, hoodies, etc.include w + d=?

About $1.25 for the wash and another $1.00 for a dryer. The costs go up depending on the size of the washer (I think the most expensive is $5.50) and how long you want your clothes drying. The larger capacity dryers cost more per unit of time.

$2.50 - $3.00 ish I usually use the large capacity units

I was there 2x while visiting. Above post is correct. Nice little place - very clean and lots of machines. I'd def go there again if i were in the area.
