That's just fantastic!
And fwiw, (knock on wood), I've had good luck buying and selling on CL. Met lots of nice, no-nonsense people. No bad experiences I can think of. If I sell something and the buyer has a problem w it, I'll usually take it back and refund, even if I didn't really have to. I think that's built some good karma or goodwill, whatever you want to call it.
Your karma is good and it's not some hippy-dippy bs, IMO. Whatever you are putting out in the world comes back. It's physics. Sort of.
