Trade CD/DVD Online

Lala is a new website which helps you buy,borrow CD online. You can check newest CD, latest play list, and also do trade CD with other people. It is cheap for subscribe your CD, just $1 and plus mail stamp fee (0.49).It is still a beta version. If you really interest about it you can go Here for direct register. It is just for USA.
P.S. I don't have any experience with Lala. According to Rumboard says after you report that the CD has arrived in good conditions you will be charged. More information you can read here.

Peerflix is similar Lala,but the different point is Peerflix just a community network, it does not has warehouse to store stuff. Like a platform, Peerflix helps its club members to do trade to each other. No monthly fee, pay as you go.

Blockbuster is an online DVD renter site. You can pick DVD on its website, it will send it to you with low charge fee.
Netflix is similar Blockbuster. It rents DVD online with monthly fee, no later fee.

Lala是一個新的網站，它幫助你在線買賣和租借CD。你可以查閱最新的CD，最新的演唱者名單，當然也能夠與他人做買賣。租金非常便宜，1美元加上49美分的郵費即可。它還處於測試期，如果你有興趣的話可以直接到這裡注冊。只適用於美國。
備注：我沒有任何與Lala打交道的經驗。據Rumboard說，只有在你報告所收到的CD是完好可以播放的它才會對你收費。更多細節請查閱這裡。
Peerflix非常類似Lala，但不同點是它是一個社區網絡，它沒有傳統上的倉庫去儲存貨物。象一個平台那樣，Peerflix幫助它的俱樂部成員去做彼此之間的交易。沒有月費，只需支付你想要片子就行。
Blockbuster和Netflix都是傳統意義上的DVD租賃商，他們都有各自的網站，會員有月費，可以不限數量。
