The order email and every notification about an order also link straight to its page.
The order page
At the top you see the order number (for example Order CC-7K2M9Q) and its status. Just after you pay you may see Confirming your payment… for a few seconds, then Thank you! Your order is confirmed.
A progress bar shows where the order is:
- Paid → Shipped → Delivered for originals, editions and handmade goods.
- Paid → Delivered for digital downloads and lesson seats.
Further down you find:
- Certificate of authenticity: your certificate (see below).
- Sold by: the shop, with a link to it, and the Item, Shipping, Sales tax and Total you paid.
- Ship to: the address the piece is going to, and the carrier and tracking number once the seller has shipped.
