Here's how I do shipping.

Tiny stuff like replacement screws and drive rings and most repair parts ship free via USPS in an envelope or a small box.

Bobbins ship in a USPS medium flat-rate box, which will fit up to seven bobbins. These cost $15 to US addresses, $20 to Canada, and $25 to other international addresses.

Spinning wheels ship to US addresses in a large box via UPS for $50. I ship to AK & HI & Canada using USPS, which typically costs $80. To other international addresses, I charge the actual shipping cost via our USPS and your postal service, which typically costs $100.

For spinning wheels being returned for service, I will reuse your box and packing materials, so the shipping charge is $20 less than listed above.

I can ship via expedited methods on request, but best we both be sitting down when the estimate comes in.

Note that international shipments will include both a commercial invoice and required export/customs forms, all of which will reflect the contents are purchased merchandise as well as the actual retail price paid. The recipient will be responsible for any taxes, duty charges, and/or import fees. If you're unfamiliar with your country's duty and tariff rates for spinning wheels, contact me and we'll sort it out together.
