Personaly I would just give it to the homeless guy collecting cans. The few bucks it brings isn't going to change your world, but it will get him a meal or 2. Unless you have a large wreck-out job, it's not worth it. Some companies try to make it seem they're doing you a favor by letting you keep all scap but may want all electronics. So they only pay a few cents a ft & you keep the scap.
Just my thoughts,
