Target is running a sale on Transformers toys this week. The retailer has marked down its Animated, Universe and Movie deluxes to $8. While not shown in the ad, Transformers Universe Ultras are also on sale for $22.49 and Voyagers for $17.99. 

Update: It looks like prices in stores are not the same as they are online.  I stopped at my local Target this morning and found that Ultras marked at $24.29 and Voyagers at $19.79.
