Posting a tube via Post Office

[proud2help]

Just created a draft listing for some model railway tracks. I have packed them in a cardboard tube that is 80cm long and meets the diameter size for Royal Mail tube service. 

But there is no option in the Simple or Custom postage options for this on EBay. The only courier I will use is Royal Mail Tracked 48 which lists it as an option on the RM website at £5.15 but not on EBay.  The largest size offered is 61cm for small parcels and a fortune for a large parcel. 

Is there a way I can just pay at the post office, mark my item as despatched and manually enter the tracking number please? 

This postage lark with EBay and all the constant changes are not much fun lately for a private seller.  Any help greatly appreciated.

That helps a bit thank you but there is still no RM  tube option.  I can though now get Yodel, Evri and Inpost, none of whom I trust.

Will raise it with EBay to try to get the RM tracked tube options added.

EBay got back to me and advised that there are 3 vertical dots when listing an item underneath the postage options where you can select a different service. I couldn't see this on the app only on my home PC. 

I did as instructed and was able to select Royal Mail. The listing went live and all looked good.

The I rechecked the listing 2 days later and had a pop up message to say my postage options had changed. 

EBay had automatically changed my £5.21 postage to Parcel Force costing me over £13.

Fed up of EBay changing listings without my permission. I have pulled the listing.
