Some part pages state "Free Shipping!!" Others do not. The Toyota Prius Shark Fin Antenna page says, "Just as with every item on the PriusChat/Shop, this item includes Free Shipping!!". Can anyone tell me for sure if ALL items are eligible for Free Shipping, even though it may not say so for that particular item? I sent an email to PriusChat 3 days ago and have yet to receive a response. Please help. Thanks!
