Kickstarter does not allow me to change a reward once somebody has selected one of those rewards. Which makes it hard to insert new rewards. At the same time, my experience with fulfilling stuff is that there are lots of people helping and ... if you say one thing but provide another thing, and there is any room left for alternative interpretation, things become less than optimal.
So when coming up with the new rewards, I embraced that I cannot change the existing rewards and selected dollar values and wording to make it clear what is offered.
That is why the "DESIGN" level contains everything in "BUNDLE" and everything in "ALLFORMATS" and so much more.
