Once you've purchased there will be an email sent to you with the vendor contact.

60% of these vendors take around 5 days to ship, whilst I'd say the other 40% take 8-10 days.

90% of them ship worldwide, however I'd be conscious when talking to them on if they can ship to you.

Anywhere from $10 to $500 depending on what vendor you're purchasing, and depending on if your purchase has pre-calculated shipping.
