Sorry, this is no longer a supported feature on Shiply.
If you know of a transport provider you would like to quote on your delivery, we can do this manually for you however. Just send an email to the Shiply support team.
The email should contain:
1) The id number of the delivery listing
2) The name of the transport provider you wish to quote on your listing
The transport provider will then be emailed with a request to place a quote on your new delivery.
