Hey Paul.
I was able to arrange shipping with the seller, I just had to do it myself.
I used Parcel2Go to schedule a pickup via FedEx Express. Package was 160cm x 21cm x 21cm, around 10kg, and valued at 90 GBP. Shipping cost was just under 63 GBP, fully insured, 1-3 business days delivery.
I had checked FedEx directly, but they were like 155 EUR. I think Parcel2Go gets lower rates due to doing "bulk" shipping.
Hope that helps.
Also, shout out to Simes for offering to help. Awesome folks, those APFers.
