You should send any CD's in a flat rate box with bubble wrap. Be sure to have the case it came in or a case of your own. The flat rate box should not be much bigger than the actual CD. This will prevent it from breaking in half. I did this without the bubble wrap one time, and the person who received it told me the CD was in pieces. So chyeah. For video games, you can also put those in a flat rate box that's a little bigger, but you may not need the bubble wrap since most game covers are pretty thick enough to protect it. Flat rate boxes can be found at the post office usually. You can also can get these types of packing boxes at Staples store usually. As for your other questions, I have never used Ebay to sell things before, so I'm not the person to ask for that sort of thing.
