I did contact the person, though. Apparently they expected to have their parent drive them to the buyer's house, so s/he can hold it securely so it didn't break.
Which it's sad to think they sound like they care about the betta in that way... or they just don't want to break it...
Anyway, I kinda wish I asked, "Well, I live a very long way away, mind if I just pay for the plant and fish and the shipping? I'll tell you how to ship him!"
Blaaaah... but I didn't do that. D: And I don't have money for shipping anymore either. (Got a new betta from Thailand. xP )
