We're going to try a little experiment over the coming couple months: every Wednesday, we'll discount one of our titles by 50%. This offer will last one day only (and we define a Wednesday by GMT-5). To receive the discount code, you'll need to follow us on Twitter (@rosenfeldmedia).

First up: we'll discount Indi Young's Mental Models: Aligning Design Strategy with Human Behavior by 50%. Yes, this Wednesday. Hope you'll take advantage of it (and help spread the word)!
