When your order ships
We pack Monday to Friday in Melbourne and ship with Australia Post. Order before 12:00pm AEST on a business day and your parts normally go out in 1 to 2 business days, often the next morning. During a big sale or a busy run that can stretch to 5 business days. That is the outside number, not the usual one.
How long it takes to reach you, counting from the day it ships:
- Australia, express: 1 to 2 business days
- New Zealand and South East Asia: 3 to 7 business days
- United States and Canada: 5 to 10 business days
- United Kingdom and Europe: 5 to 12 business days
- South America: 10 to 15 business days
These are estimates, not guarantees. Customs and peak periods add time.
If the tracking stops moving
Once your parcel lands in your country it is handed to your national postal service, and our tracking link often stops updating at that point. That is normal: it has not been lost, it has just changed hands. Take the same tracking number and put it into your own country's postal site, which is the live one.
European Union
Since 1 July 2026 every commercial parcel is assessed regardless of value. Your carrier collects import VAT plus a flat customs duty before delivery, and will contact you by SMS or email with the amount. Please give us a mobile number at checkout so they can reach you, because a parcel they cannot reach you about is sent back.
