Just looked into ordering some of the adversary decks on the webstore as nowhere in the UK stocks them, nor can they order them apparently as Esdevium don't understand the POD service FFG offers on these decks. It's going to cost more to ship them to the UK than it is for the actual decks! This is insane!
The postage cost makes the decks totally not worth it.
$28 for the decks, $32 for the shipping. Then there's sales tax to add on too, and customs charges because the cost of shipping pushes them over the threshold... This means that all told I'm probably looking at £60 for them, so about $75 for 4 decks.
Not going to happen.
