Are you familiar with Kickstarter? Basically, it's a preorder platform for creative projects. Authors use it as a way to offer special editions of their books, hardcovers, physical omnibuses and more.
Each campaign has a time limit to fund (typically 20-30 days) and backers pledge different dollar amounts for different tiers that have scaling perks.
For instance, a lower tier might offer an ebook or a book mark, while a higher tier might offer signed hardcover copies with sprayed edges of an entire series (plus all the swag and goodies offered in the lower tiers).
Once the timeline ends, if the Kickstarter is not funded, no one is charged and no rewards are delivered. If the Kickstarted is funded, the backer is then charged their pledge amount and the creator sends out all the goodies!
I have been thinking of doing a Kickstarter sometime in the near future, so I wanted to educate you about them.
