In 2014 the B. F. Skinner Foundation is celebrating its 25th anniversary and 110th birthday of B. F. Skinner. Throughout the year we will have different promotions and giveaways on our website, and we are starting today by introducing a limited-time 50% (!) discount on Schedules of Reinforcement by B. F. Skinner! The book was originally published in 1957, and reprinted by the Foundation in 1997. Between April 1 and May 21, 2014 it will be priced at $12.50 at our store (plus shipping).
