Keeping Absolutes in Mind—I think donating money is still somewhat underrated in discussions like this, though I was happy to see it brought up in several comments.
Consider taking the GWWC pledge or TLYCS pledge (easier / more flexible) or some other pledge if you feel like that would help with keeping motivation up.
You could also organize or contribute to a local group. Regular local group attendance could also keep motivation up (and would be a lot less costly for your budget).
Even a small donor can make a real impact for individuals directly, or help get small or new projects off the ground.
