I given people burned audio discs as trade for various services - helping fix my car, doing me favors, buying me beers, etc... Its always been a thing between friends, and always the choice to the recipient of the CDRs...
But I've actually given away more than I've ever traded... I recently dumped about 200 PH CDRs onto some recently married friends as a congrats... Afterall, they did feed me and get me drunk at their wedding!
I've also taken 1000s of analogs and several 100 CDRs up to the bar and given them away. Some folks buy me a beer as thank you. Some gave me nothing...
I think, yes, the materials have some value, and yes, in a economical sense, you are losing money giving them away... But the Karma you get from it, as well as the props from total strangers and friends is worth it...
That's all the "trade" I need...
