Once you place an order, you'll receive an email with your order number and an upload link. From there you can upload your content and artwork. We have a HUGE 20GB transfer limit which is more than enough to handle any project. We can also accept the content and artwork all in the same transfer! Here is the upload link: https://trainrecords.wetransfer.com/  Note: At any time you can also upload the files to us using the Upload button, it's under the "Resources" tab on the main navigation menu at the very top of all our website pages.
