Not sure if news of this had been posted already, but just saw on the Target site that they have a $5 off Transformers coupon (on transformers $19.99 and up). follow the printing instructions (had to update my Java).
Also, there's a $5-off coupon on Kre-o as you'll see on that page. I doubt they'll let you double dip and use both coupons on a Transformer Kreo set.
