I saw something really good on LessWrong the other day. There's a link you can follow so that 5% (10x more than the 0.5% from Smile) gets donated to charity. I think it uses the affiliate link system, but I haven't really looked into it. This LW post explains it:
It's not the EFF, but if you believe in GiveWell, it's a fantastic way to make a sizable (and mostly passive) positive impact.
And the best part: It's stackable with Smile. Presumably, EFF could set the same thing up. (I believe Scott Alexander of SlateStarCodex.com has one set up to support his site as well, so it can't be that hard or restrictive)
