Can I switch which box type I want for the month? (Seelie to Unseelie or Vice versa)
Yes. Sort of. 😉
To switch boxes the first time, you will have to cancel your current subscription, then resubscribe to the box type that you want. Unfortunately, that’s the only way to start with.
After the first time doing this, you’ll be able to turn each box subscription on or off as needed in the future from your account.
(And yes, you can use a coupon for the new subscription the first time)
