Redeem all 4 albums to boost their sales. Then here some options to do with the others: 1) Give Copies to Friends 2) Go to your local record shop and sell them. You might only get in store credit but you should get enough credit to at least buy 1 new album 3) Donate them to a place like Goodwill and you will make someone's day who might happen to be a Linkin Park fan looking through CDs at a goodwill. I know I have bought a lot of CDs through goodwill because I used to find a lot of good CDs I never owned physically and it was cheap enough for me to justify buying them where I normally wouldn't have. So to all those people that donate their CDs, God Bless them. 4) Save them and use them as birthday gifts.
