Frequently asked

Does it arrive assembled?

Yes — we assemble, calibrate and test-stitch it in Miami before shipping. To protect the machine during freight, the head ships detached from the table; remounting takes minutes and we can walk you through it by phone.

Can I finance it?

Yes. You can split your purchase into monthly payments with Affirm (checking your rate takes seconds and won't affect your credit score), and Synchrony offers special financing on qualifying purchases (subject to credit approval). See your options on the financing page.

Do you ship to Alaska, Hawaii or Puerto Rico?

Puerto Rico: yes. Freight is $150, and it's free on orders of $3,000 or more.
Alaska and Hawaii: parts and accessories ship there fine — USPS or UPS rates are calculated at checkout. But an industrial machine travels on a pallet by freight, and those two states can't be quoted automatically: get in touch before you order and we'll give you a firm price. +1 (954) 681-3894 or contact@suprasewing.com.

Warranty & support?

Yes — on top of the manufacturer's warranty, Supra Sewing backs your machine with our own coverage: 90 days on mechanical defects and 12 months on electrical & electronic parts — and since this is a Speedway, your electrical & electronic parts are covered for 18 months, serviced by our in-house techs in Miami, FL. Support in English & Spanish: +1 (954) 681-3894 or WhatsApp.
