Your confirmation email will have a preview file and link you can use to check and/or edit your print.
Any editing needs to be done within 24 hours of placing your order if using standard or free shipping and within 4 hours if using express shipping. After that time the order will be in the print and qulaity control process so will be too late to edit.
email firstname.lastname@example.org for any urgent requests and we will do our best to help if there's still time. Otherwise we can offer you a reorder for a very discounted price.
Hope this helps
