I suppose I do quite a bit of freecycling, but not by giving away or trading. I go curb hunting in my city a few times a week and find lots of stuff. I don't keep it though, except the rare thing I may need (like finding a working iPad w/o a password with its charger) from the recyclables. I sell almost everything I find. I'm just starting to blog about it if you check out my post linked above about the TV I found as an example. I sold one of those parts last night for $73.99 revenue, minus fees and taxes.

Great to hear that you're able to save those types of things where you're based. Every bit adds up.
