Someone managed to grab a screenshot of the pricing before Backerkit imploded
Here’s the thread, there are some shots of the shipping and Radiant Packs as well https://www.reddit.com/r/brandonsanderson/comments/1b7aw0u/for_those_of_you_waiting_on_the_wor_leaderbound/
its worth noting that all of these prices don’t include VAT or Shipping costs (even if backerkit has your address).
These will all be calculated once the campaign has ended. I assume this means you can back out at a later stage if the shipping prices/import duties etc are awful (which they will be!)
Shipping costs for the set bundles are listed on the campaign page. If you want add-ons, that will be extra and calculated later.
It does say somewhere that Dragonsteel will cover import duties for all international backers.
So really, the only unknown is shipping for add-ons. If shipping cost is a stress, maybe stick to the bundles with fixed shipping costs?
Yep, I think this was posted while the site was still down though.
