Take it as you will, But I'm not going to gift someone 600+ dollars and hope they are honest about shipping me something, having it paid as a Goods and Service allows a much better paper trail, and much better buyer protection.
I have 3 confirmed trades on /r/hardware swap, not a lot, but better than nothing.
