Seattle - Amazon.com has added Kindle and e-books to the list of CE products it will accept through its pilot trade-in program.

The project, still in beta-test phase, provides Amazon.com gift cards in exchange for pre-owned electronics, DVDs, Blu-ray Discs, video games and textbooks

Accepted CE products include cell phones, GPS devices, digital cameras, tablets, MP3 players and gaming hardware. Amazon provides free shipping for the items, and offers "very competitive trade in values," according to a company spokesman.

Kindle was added to the eligibility list in response to customer feedback, which indicated an interested in trading in Amazon's proprietary e-book reader for new, upgraded devices, the spokesman noted.
