Too late now, but with most Kickstarters, as long as you leave your pledge in for $1, it will give you access to their pledge manager when it goes online months after the campaign ends and you can add things then. I've had to do that for several games in the past.
Yes. Solid advice.
Don't cancel your pledge! You'll have plenty of time to save your pennies. Otherwise...the Embers expansion sold out very quickly, and I bet it will again. You may not have another crack at this for a long time. Plus, you'll be missing out on the Sellsword. That was something I've had to suffer, but not any more!
