So I am new. It sucks.
Any suggestions for a newbie?
Suggestion.
Follow through when you make a commitment.
Don't waste people's time telling them that you have a MP and then after escrow is set up say that you need to go purchase the MP.
Don't waste people's time telling them that you'll be back to provide the MP code, and then cease all communication.
You've wasted people's time, and you've caused them to waste money on transaction fees.
