Our domestic orders ship three ways; to take them one at a time:
Plans/DVDs we ship First Class mail through the USPS. Shipping/handling is $4.95 unless you buy more than 75$ worth of items, in which case shipping is free.
Kits ship via UPS ground, and like all orders over $75 they ship with free shipping anywhere in the continental USA. Depending on the weight of the kit, we usually charge an extra $25-$50 to ship to Canada. There may be similar charges for shipping to Puerto Rico, Alaska, Hawaii, etc. If so you will receive a notification after checkout.
Orders that are larger than plans but smaller than kits will usually ship Flat Rate Priority Mail if they'll fit in the envelope or boxes, or UPS Ground if they won't.
We ship anywhere in the world; for plans/DVD sets the cost is $6.95. Plans ship USPS First Class International, which "officially" is 6-10 days. To first world countries it usually is. To second/third world countries it averages closer to 3 weeks, up to 6 weeks. Most of the delay is usually due to customs and their local mail system.
We ship kits via USPS to all other countries (except Canada and sometimes Mexico) via Global Priority Mail. All those countries are strongly encouraged to buy the international kit which includes only the items that are difficult to find locally, in order to keep the weight down; and the international kit includes free shipping anywhere in the world *if shipped by itself*.
In other words, if you buy an international kit and a clay bit, you will have to pay a small shipping surcharge for the clay bit. Generally shipping surcharges cost me about $15/pound ($35/kilo), which is what I pass on to you.
If your purchase will involve a shipping surcharge we will contact you once we receive your order to explain the difference and provide a bill if appropriate. We list the actual cost of the item on the customs form, we cannot check "gift" or "sample". We do not list shipping costs, and on items with free shipping we deduct the shipping cost from the stated value, to save you as much local duties as possible. However, you are responsible for all necessary customs, duties, import fees, that your government may impose.
