So you don’t have a use for those old clothes or other stuff around the house, but they’re in good enough condition that someone else could use them, send them off to your favorite charity.
This is especially true for clothing. Clothes that are still in excellent condition can be resold. But charities may also take clothes that aren’t in such good shape and turn them into cleaning rags. You can do that around the house too, just be sure that they really have reached the end of their life span as clothing.
You may also be able to find people in your area who enjoy doing crafts and need old clothes to make rugs and such.
Another option would be to hold a garage sale and sell the stuff yourself.
Non-clothing goods can be more difficult, especially if you’re talking electronic goods. Look around for a good electronics recycling program.
Don’t forget to consider reused items when shopping for yourself. Thrift stores can have amazing deals on really wonderful clothing. So much more affordable than going to department or specialty stores.
