Recycle Your Electronics for Books- No charge for Kindles

Here is an interesting story on a recycling program being held at Andover Bookstore.  The program will charge $1 per/lb for unused electronics equipment with 5% of the cost going toward a gift certificate to the bookstore.  What is interesting about the event is if you read the list of items they accept it says, “ accepting Kindles and cell phones at no charge.”  Really?  Kindles?  How are ebooks more environmentally friendly with such rapid device obsolescence?  Event could be a good traffic generator for the store, though.  Would be interesting to know how the event turned out.
