I agree Yoyo, the education book market stinks !!
Pushing new editions every 2-3 years and jacking up the costs with < a 5% difference in content ! Maybe some new photos or drawings, but how hard is that . . and it doesn't really change the "message" (concepts presented) !! mad

It's ridiculous that some of these texts cost between $200-300 EACH !! What a crock !!
