Shipping costs have increased dramatically over the last few years. We will not make any money from shipping. We print in the US, then ship international in bulk to the UK, and ship out to the rest of the world from there. (We actually make a quite a loss on UK shipping)
We understand that international customers might not want to pay $30 for shipping. If you'd still like to help out, you have three options: pledge at an ebook-only level, persuade your store to pledge, or wait until the book is released and buy it then by mail order or from your FLGS. We won't know what the price will be on release until the kickstarter is released.
We've been careful not to add any stretch goals that delay the main book, and we're using reliable freelancers to write the bulk of the additional material we've added. We don't expect the unlocked goals to delay our delivery date.
If we end up unlocking the $100K goal "full color rulebook," we expect that delivery dates will be pushed back by roughly a month as the art changes to full color.
