Candy Japan guy here. Japan Post announced that there will be price increases, which seemed to more than double the shipping cost. Even if I could ship (haven't checked lately if they opened yet or not), the service would need to change. Probably going from twice a month to once a month while still costing the same, so not sure how attractive that would be to subscribers.
While the site was down I started working on some other projects which are looking promising, so I'm dragging my feet a little bit about restarting it (I already refunded everyone's candy balances in case I never restart). Since I spent 10 years curating candy I also got a little bit tired towards the end to be honest.
I should probably make some use of the organic traffic it's getting though. I've actually had more traffic from Google after I could no longer ship. Thinking of selling one-time boxes on the site instead of subscriptions, as I could then spend the time I used to spend on curation on new projects instead.
