Just to clarify – This is a THW Kickstarter and Acheson Creations and Rebel Minis are the manufacturers I chose to buy figures from to fit the Lost Lands rules. Just like when a board game is created you use a board game manufacturer.
It's covers the new rules as well as the new figures, the five adventurers – the other figures in the set were added to make a complete party without having to order three different packs and maybe more figures than needed.
US postage is actually included in the 100 USD pledge, there was a hiccup in the first one. You are correct, the additional $10 USD helps to cover the additional cost for international shipping.
The 39 figures include the dinosaurs and mammals that are packaged as a set and not offered as a set elsewhere.
Bought separately, the rules, figures etc. and shipping from 3 manufacturers is more expensive. It's set up as a one stop-shop package with roughly a 20% discount over what it would normally sell for.
All the figures, even the Stretch Goals will be available after the closing and from each manufacturer but at a higher cost.
