Today only, as part of their Mega Monday Sale, Mattel is offering free shipping and an extra 20% off any toy purchase! The discount and free shipping will automatically be applied at checkout so no coupon code is necessary.
This promotion will even work on clearance items. So, maybe check to see what you can score. It looks like prices in the clearance section start at only $2.09 before the 20% discount, so you should be able to get some great deals.
