Most of my donations go to Goodwill, as it is only a few miles away. Occasionally, the Salvation Army will call & do a pick up in the area. I always try to gather up at least 1 bag for them.
Electronics & hazardous materials are taken to community drops whenever they are scheduled.
If I have large pieces of furniture or other items that are not in good enough condition for Goodwill or Salvation Army, I have paid to have them hauled away by a junk service. They recycle what they can & properly dispose of what's left.
