20% Toys at Amazon: Includes Barbie Dreamhouse
Amazon apparently is taking 20% off all their toys sold directly by them using promo code: AMZNTOYS at checkout.
I used it to buy my daughter the Barbie Dreamhouse, at first it wouldn't take on that item but then I used the regular packaging option instead of e-commerce when adding to cart and it did take the coupon. $169 was already the lowest I had found anywhere, but $135.20? Won't beat that.
Works on a ton of other toys too!
