When I originally backed this campaign I was in a tight spot financially, so I wasn't able to add on all the add-ons I wanted. So I was just wondering if any of the add-ons will be available for purchase beyond the campaign, I was hoping to pick up Prop Set 1 and the File Folders, they seem like really cool additions. Which if any of the add-ons will be available in the future? And where would I be able to pick them up?
