Shipping is a flat fee of AUD$18 (unless delivering to Australia - see below). I should be able to deliver to most countries. If there may be an issue, I will contact you.
I'll send everything as a standard international parcel via Auspost which will probably take around 2-4 weeks to arrive. You can check out their delivery times guideline if you need a slightly more concrete delivery time frame. Parcels are shipped out from Melbourne, Victoria.
I will try to send out stuff as quickly as I can manage it. However, time consuming processes like 3D printing, soldering and waiting on parts can delay postage by a few days but I'll try to make it as clear as possible before ordering if this is the case.
If you have an Australian postal address, I may be able to partially refund some of the postage costs since it's significantly cheaper to post domestically than to post overseas. I will contact you after checkout if you have an Australian address. You can also leave a message to me during checkout. If I don't recieve any response or instructions within 2 days of payment, I'll send it via express so you're getting as much of the $18 worth of postage as possible :)
If you're paying via Bitcoins, the price of shipping is currently ≈BTC$loading....
