They give you a shipping label to print out towards the end. And you have to pay for shipping and for a envelope. The $2 credit really won't cover shipping though. If you send it Media Mail, the postage is about $1.84, insurance is another $1.30 (optional) and I paid $0.30 for a bubble envelope. If there is a specific time they have to receive the games by, media mail may not be the best option though since it can take 5 - 14 days for them to get it depending on where you live. I live 30 minutes from where the package was being sent to so I figured it wouldn't take more than 2 days for me with Media Mail. You can send all 4 games in the same package.
On a side note, I got my 2nd set of codes today so I have $104 to spend.
