So, correct me if I'm wrong, but it would seem the only truly anonymous way to purchase Bitcoins would be offline in some form or another, be it cash or trade. Are there no prominent cash-by-mail for Bitcoin services left? It seems most of those that offered that service have stopped it. Is it that unpopular or misused?
seems to be faster to go to a walmart and use bitinstant...
Only problem with this is you have to trust Walmart
They could stop selling them at any time though, due to 'internal/regulatory/government' pressures.
