Our system can process any card that bears a major card brand logo (Visa, MasterCard, Discover, JCB, Diners, AmEx.) and Paypal.
It does not accept pre-paid gift cards. Even though we can process them, this doesn't mean that the banks will allow the transactions to go through. Prepaid cards might run successfully on one-off transactions but are often declined on recurring transactions.
In order to still be able to get a Loot Crate, you can purchase a non-recurring 1, 3, 6, or 12 month package at http://gifts.lootcrate.com
Please note that all subscriptions are billed in full for the subscription amount upon sign up.
