I son't have the energy to garage sale.
I generally donate goodwill and what they won't take, or all the crap I Freecycle. I love love love freecycle because I do not like to throw things away. & I rarely do anymore.
I find it super convenient as well - I just leave things on my doorstep all the time for freecycle people to pick up. I tend to post things a few at a time though because it does take a while to sift through responses.
A garage sale and then freecycle/donate I think is a good idea. Get some money and then easy way to get rid of the rest.
