Eu perguntei ao @Storium no Twitter:
@Storium quick q: if I pay $10 for Beta Player access, do I later have to pay the full $40 for The Deal access, or do I get a discount?
, e esta foi a resposta :
@adrianovaroli You can upgrade at any time (up until our public launch) and only have to pay the difference!
Também pedi um link para essa política e a resposta foi:
...if you back us at $10 and then go to your profile page, you'll see the price-adjusted update options listed.
