Thought i'd go back and have a look myself.
I had some earlier orders of 1/6 and 1.5 pieces which were between $10 and $15 to ship to the UK.
Bu the first LARGE box and heavy piece i got was probably the Batman PF in 2012.
$18 to the UK.
Now lets compare to my Guyver 3 which is also 1 large heavy box to the UK, shippe djust a few weeks ago.
Ouch.
Looking through, i had the Museum pose Green Lantern PF shipped in 2015 just 3 years after Batman and shipping was $85...
The last Sideshow made PF i had shipped direct was Thor Breaker of Brimstone and that was $146 and that was in Feb of 2019.
