We ship plans world-wide free of charge.
For parts, shipping charges are reasonable, and is meant to cover my expenses, which includes envelopes, boxes, packing material, Paypal fees, postage, and insurance/shipping confirmation charges (when warranted). Shipping charges are based on order weight and can vary from $4.00 to well over $20. If you purchase a lot of small parts (like magnets, Hall sensors, plug clips, etc), the Paypal shipping calculator may over-charge you.
I always try to be fair, and if you are overcharged by more than $3.00 or $4.00, I WILL SEND YOU A PARTIAL SHIPPING REFUND via Paypal.
