Many of you know I used to buy back DVDs and CDs directly from consumers and then re-sell them on Amazon, using FBA -- I still love the concept.
I guess it was just a matter of time before Amazon copied me :) It looks like they just recently launched their new trade-in store for DVD Box Sets and Blu-ray Discs. I'm hearing rumors that they are buying back around 1,000 units a day right now without any announcements. Imagine if they actually did it the right way.
Earlier in the year they launched the Buy Back/Trade-in concept with Video Games and apparently it was a success, so expect the program to expand to Text Books soon and then from there consumer electronics and much more.
