This won't fly.......... good try youngins'
Ah, there's "play it again sports" for the person who wants to sell their old sports equipment -- why give it away as they say in this article? Back in the 1800s this was a good idea, neighbor helping neighbor, but now? Hey, if you want to give your neighbor or sports acquaintance something, sure, go ahead; but on a broad scale this won't work. It would take a municipality to do so, such as a city adopting a bike-exchange for the free usage of bikes for commute.
Nice try, it's a complete wast of time. Remember, people like "new" and they like to shop. I'm not talkin' grunge here, i.e., the 19 year old going to good will for a used pair of jeans, nope, I'm talkin' about being a real human who wants "new" , and who doesn't? The automobile is the only area I can think of where buying new is not a good idea, maybe here I would go three years out, after depreciation has taken its' course. And if you do go this route you'll be always known by your kids as "Mr. or Mrs. Cheap Skate", especially if mommy or daddy work for the government, with all the freebies they're already getting, of course bottom-feeding is a complete and other topic.
God save America.
