I have noticed many ex-WAMU branches used to have the once per 12-month period promotions. Perhaps they are just not used to this promotion based on calendar year?
Last week, I successfully persuaded one of my co-workers to take advantage of the promotion before the end of 2009. As I expected, he said the banker had never seen this offer before. So I would speculate the knowledge of the banker in this promotion is minimal, if not none, and I would probably ask the banker to reread the coupon.
