The saying goes, one man's trash is another man's treasure. It's the guiding principle behind garage sales. I'm lucky enough to live in a city where every sidewalk is a garage sale of sorts. Someone is always moving, getting rid of stuff, having no place to put it. Then, if you're savvy enough, you can find something priceless for free.
It's amazing just how much stuff there is in the world. It always occurs to me when I move. "I don't have that much stuff," I think until I am surrounded by boxes full of stuff I apparently own. Humans tend to expand to fill the space, like a gas. The same goes for the internet. There is a lot of junk out there. Lucky for you we've sorted through a lot of it to give you some good stuff. And on the cheap, too (if you consider free to be cheap).
