Yes! You can have as many subscriptions as you want! Actually, we suggest that you make this your go-to gift. For the gifting karma purposes, of course.
If you only want one subscription, please be sure to check your account before you add a new subscription to make sure you don't already have one. If you cannot see your subscription in your account please write in to firstname.lastname@example.org so we can help you out.
And if you scroll down the page, you'll be able to see plan options!
