Cratejoy is a great way to get visibility for a subscription business if you're new. The site offers PR opportunities as well for business owners, if you jump through all of their hoops to be featured.

It fills a critical niche in being one of the only services built around monthly recurring services. The Marketplace is a good selling tool too.

Literally nothing they take your payment and provide a terrible service. I have 4 subscription boxes with cratejoy and they have terrible service and a terrible support team.
