We hear you on all of these requests, and we are currently working on adding more reward levels. The reason we can't do this instantaneously is that new items affect shipping rates. So, before we can sell, we need to run some numbers with our distributors.
We are also working to set up a way for backers to add items to their orders after this Kickstarter has ended. We will post updates here, so keep an eye out.
Unfortunately this is trickier than you might imagine. For folks in Australia, it will overall be cheaper for you to just buy the Mini-Book Two-Pack and pick up Soonish in October locally. It will have the UK spelling (or as we keep being reminded by some of you, the correct spelling).
If you are in Canada and you want the UK version, you're pretty much in the same boat. The short version is that the "US Edition" is really the North American edition. If you want the UK edition with its "correct" spelling, your best bet is to buy a copy online at one of the sellers listed on our UK page.
Not via the Kickstarter (it's complicated), but you can pre-order now from the sellers listed on the Soonish page (http://smbc-comics.com/soonish/). You'll receive it in October along with everyone else!
Yes! Sign up for the mailing list via this google form (https://docs.google.com/forms/d/e/1FAIpQLSfAX-9bfv06hXIbLGMxI-u8X2MwNclPVWvkdnW1FCz2ptjW0Q/viewform?c=0&w=1), and list your retailer as "Kickstarter" and your backer number as the order number.
But please note: physical rewards are a special offering from our US publisher, and are thus only available to US customers/backers.
