Sorry you had problems. But "FREE" means free....So...unless the description says "free portion of the order" requires additional shipping costs, then they did not fully disclose terms of order. Some companies/ orders are very sneaky about this. It is as if they make their money on shipping charges. I myself have seen that sometimes a person will order an item, but then, "shipping" is charged & the item shipped is not equal to the charge for shipping.... Don't know if that makes any sense.....but IMHO those are my thoughts
