Being a new convert to Xbox 360, I've been thinking that after I play through some games I'll probably want to get in on the game trading action or selling "previously enjoyed" games on eBay. So, how do you guys use to ship your games? I'm not just looking for a suggestion for a courier here. I've been using UPS for years, and I have no issues with them. What I'm looking for here is a suggestion for packaging and shipping. i.e is the best method to buy a dvd mailer package and then ship via a courier, or does USPS have the right size box and a good rate? I'm looking for the best combination between fast, cheap, easy, and reliable (the first 3 mean nothing if the courier loses/damages the package). What are your personal experiences, and what do you recommend? I'm open to using any of the couriers, but I prefer UPS and USPS. I have a post office very close to my house, but given the small size of a 360 game I'm hoping it might be possible to get some sort of pre-paid mailer that would allow my to drop the package in the mailbox, raise the flag, and forget about it.
