UPDATE: Sale has changed but prices are similar. You can stack two codes so choose the ones that work best for you. (These codes are valid on everything, not just toys.)
With Kohl's card: APRILMVC-15%,
With or without card: SHOPNOW15-15%, NEW6107-10%, FREEAPRIL-free shipping
May work: THANKS1498-15%
I would try to stack the two 15% off codes and pay the 99 cent shipping.
Kohls has select toys buy 1 get 1 half off. Most of them are Melissa and Doug. *If you have a Kohl's card you can also apply coupon code APRILMVC for 15% off and code FREEAPRIL for free shipping. If you don't have a card you can use NEW6107 and shipping is 99 cents per item.
You can get the Melissa and Doug bread set and the stir-fry set for about $20. Amazon's price for the two sets is about $33. Other sets are available.
