Options like color and size on your subscription are called variants and they can easily be changed by logging into your account at cratejoy.com. These changes will reflect immediately on your account and future shipments.
Log in to your Account page and click "Subscriptions"
Click "Manage Subscription"
Click "Modify Plan Details"
You will then be taken to your customer account page on the Seller's website. This page lists all subscriptions you have for just that store. You can also change the product or prepayment term for you subscription, but these changes will not reflect until the subscription renews.
Click "Edit" on the subscription you want to modify
Choose the new variants.
If you only want to modify the variant, be sure to select the same product and term to which you are already subscribed. If you pick a new product or term, that change will take effect when the subscription renews.
Click "Change" and "Confirm"
