I've been gifted things here and there, without asking. One of the biggest things, when I first started, a guy at the track gave me a lightly used pair of rear 1/10 buggy tires with about 60% tread left on them. It was a huge help as my current tires weren't right for the track.

I'm not hurting for money, but I do have a budget. Most of my stuff that's nice enough to sell, helps fund the new stuff I buy. I've paid it forward every once in a while with smaller items, rarely online though. I've never seen a thread like this on RCU.
