I absolutely wanted to order The LEan Startup-book from http://lean.st/. I read that they were running tests on the site, in lean startup fashion – testing whether different features worked and whether some did not.
One experiment is adding ebook version for $12.
However as I was making the order it failed.
I tested different browser combinations and it repeatedly failed.
As I have seen the offer, which includes also the ebook – I sure am not going to buy just the dead tree book for $25, as most of the time I would be reading the ebook anyway!
Waiting for it to get fixed.
