A colleague recommended Pip Coburn's book, "The Change Function: Why Some Technologies Take Off and Others Crash and Burn."  It looked terrific so I decided not to wait and have it shipped home, but to buy it right now while traveling.  I did buy the book, but now I want to know why B&N's in-store price is 25% more than its online price?  Is that really the differential for the brick and mortar business?  Or, is it the penalty for impulse purchases? 

And, can anyone tell me why the B&N sales clerk in the Georgetown store claimed to be checking the internet and then insisted that the difference in price was for the paperback version?  There is no paperback version.

Guess I'll be shopping Amazon until I cool down....
