A few months after the book launch, some marketing manager at Barnes and Noble decided to do a 50% off any book promo, not thinking too hard about it and it instantly spread through all the foodie forums.

Later on, they did the same promo but Modernist Cuisine was prominently listed as a book the promo didn’t apply to.

Anyway, that, my friends, is the story of how I made $313 impulse purchase.
