If you aren't sure, maybe you could use Paypal. That is a convenient way to purchase something and may provide you with a greater sense of security.
I have exchanged GCs with several members and had a very positive experience each time. I have not purchased anything from another member.
One member gave me their Cinemark GC (no places that accepted it in their area) and I offered something in return. They insisted that they did not want anything in return.
Each morning when I open my eyes I say to myself: I, not events, have the power to make me happy or unhappy today. I can choose which it shall be. Yesterday is dead, tomorrow hasn't arrived yet. I have just one day, today, and I'm going to be happy in it.
