We can't make edits or changes to orders once they have been submitted, so sorry! We'd be happy to cancel your current order so you can place a new order for the print or product you prefer, so long as the order hasn't shipped yet.
Just emailed us your order number, what you'd like to cancel, and we'd be happy to help you out. firstname.lastname@example.org
If you need to change your address, just email us your order number and the correct address. We can usually change the address before it ships.
