Typical port donation amount?

[GeinHealy]

I accept any donation and say "thanks" no matter how small the donation. I always group, port, and then accept donation. However, if someone responds to my: "porting for donations!" and then just runs off or gives me: "no money on this toon, lol!" Then they're put on ignore. Not many are that stupid, but there's some.

I know who always donates 50pp, 100pp, or more and if I happen to hear them asking for port, I'll switch to my druid right away if I can.
