The box subscription business model is getting harder and harder as competition increases. I can relate on two points with my own Japanese tea-of-the-month subscription (https://tomotcha.com):

- At one point customs were very slow to clear in Germany (one to two months), though shipments never actually bounced back. Paying for tea and not getting it is frustrating. Then eventually it arrives, two months late. We lost customers because of it. Eventually that problem went away and now shipments are going through as usual.

- Competition: we used not to have too much competition when we launched 3 years ago, now similar services are aplenty. It hurts conversion rates, a lot...
