I suggest you call the store throughout the day because they have to wait for the goodwill truck to go & pick up their donations from the day before, that way they can have room to accept new donations. The only thing is the truck can get there anytime.
They accept books here, but I'd advise getting there no later than 9:30 to get in line to donate. They start taking donations at 10, but they fill up fast, usually after 20 minutes or so they won't take donations until the next day.
