This Goodwill is the primary place I get work slacks. Thank you donaters for allowing me to dress for success for less!
They have racks of slacks, khakis, blue jeans, skirts, dresses and shirts. Waiting for a dressing room can take forever, but there's nothing you can do about it, so just look at the 70's ties while you wait. There's a reasonable selection of shoes and accessories, as well as home wares and electronics.
In addition to hunting for Halloween costumes, they also have a decent selection of holiday decorations that are fun to pick through.
