      Shipping is free in the USA and Canada! Yes, that is correct, we will ship your kit at no extra charge. The price you see is the price you pay. USA residents: your stud kit will ship via DHL Express (2-3 day service). Canadian Residents: your stud kit will ship via Canada Post Expedited service. If you're a Canadian and want to be quoted in CAD, please contact us for a personalized quote. If you order through the website here we pay the tax.

     If you're not completely satisfied with your stud kit, ship it back within 30 days of order date for a refund of the original purchase price minus 20% for restocking. You must call ahead for a Return Authorization number and a return address (do not ship to our shop). The kit must show no signs of use for a refund to be granted.

Express Shipping
