When you put a package on layaway, you are able to pay a percentage at any time in multiples of 10. 10%, 20%, etc. Your reward are based on the highest pledge you have paid off at any time so, if you were to put $100 towards the Magistrate pledge, you will have paid the equivalent of the Founder package and are entitled to the contents of that specific package, even if you never finish the Magistrate layaway.
