For each credit and debit card transaction, an industry-standard processing fee will be applied to each purchase. These fees will be charged in USD and are clearly outlined in your checkout screen.
For crypto payments, standard network fees are applied on top of order totals. For example, if using ETH to purchase, gas fees will be directly from the Ethereum network and will be set like any other ETH based purchase.
If you're using a Coinbase wallet, the network fee based on the blockchain you’re using will be applied automatically by Coinbase and the total amount will be shown before completing the checkout. If you're using any other wallet, the fees will be applied via your wallet's interface.
