I've never used MoneyGram.  If I can get cash in hand from MoneyGram without it going through my bank account, paypal, or debit card, then I'd be willing to sell 3 BTC.  I'll look into MoneyGram today and see what I can learn about it.

Other payment options I'd be willing to accept:

• Face-to-face cash exchange
• Cash in mail
• U.S. postal money order
• Western Union
