Sorry for the lack of posting. I’ll be short and just take this post to recommend a book I’ve been reading, titled ‘Predictably Irrational‘ (home page). The book basically covers a wide scope of consumer and social behavior. For example, every buyer decides whether or not to purchase something by weighing the positives and negatives. By including the word “FREE” into your promotions (like free car wash with gas, buy one get one free, etc), you greatly decrease that negative consciousness and thus increase your sales.
Definitely a book worth reading for 2009.
