Ethereum (ETH) is a blockchain technology that allows for payments with the digital cryptocurrency, Ether. We use a secure platform called Coinbase to process these transactions safely, easily, and quickly. To pay with ETH, click the "Coinbase Commerce" option on the payment page at checkout. You will then be redirected to a portal to login to Coinbase, where you can initiate the transaction. At this time ETH payments are not available for subscription orders, only single purchases. Please note that all refunds will be processed in United States Dollars (USD) and not ETH.
