Our website estimates a shipping amount. For smaller orders, with smaller items, where the value is under $1,000, the website calculation is usually accurate and we will send paid for orders immediately. If the website has charged alot less than the actual cost, we may ask for an additional payment to that we recover the actual cost of freight. For larger orders over $1,000, or for orders including larger items like Crane Humidifiers, we will need to quote shipping separately, or offer you the opportunity to arrange your own shipping with your own logistics carrier.
