Target is having an in-store promotion: for certain brands, including Transformers, it's Buy One Get One 50% off. It was yesterday (the 6th) and today (the 7th).
This stacks with the 25% off one toy coupon.
I used this to pick up Masterpiece Movie Ironhide and Sky Lynx. It takes the 25% off Ironhide, drops Sky Lynx to $40, and then redistributes the costs to both (in case you return them). On the receipt, it lists Ironhide as 71.99 and Sky Lynx as $63.99. Additional 5% off if you have a Red Card.
