Most generally they take anything however the folks there are volunteering and have to sort and throw away the items dropped off. The discarded items big or small still have to be disposed of by way of landfill or other means. Absolutely donate it if it's useable, but remember they have to pay to throw stuff away just like the rest of us, whereby driving prices up and making more work for the folks giving their time. :)
Yes they seem to accept most anything
