Mass Effect 3 Collectors Edition disc 2 replacement

[Frosty The Batman]

So my friend borrowed my disc 2 so he could play online with our friends. He says he's fine with the $10 fee cause he'll buy the game used someday. Long story short, he lost my disc and gave up looking for it after never even playing online.
How would I go about replacing it?
I've already told him he's gonna have to buy another copy of the CE and give me the disc.

Not sure if people are doing it anymore lately but on eBay people were reselling the first and second disc separately for all the complaints people had trying to remove the discs and cracking them in doing so.
