Second Nature (formerly FilterEasy) accepts all major credit/debit cards for payment. When you update your information and select your interval, we will charge your card only on the requested order dates. Even though we give you a convenient breakdown of your cost on the site, you are charged only on your order dates. Once your payment processes, we begin processing your order for shipment, which generally takes 1-2 days to get out of our door. You will see a $1 pending charge on your account upon signing up or adding a new payment method, but this is only to verify your card for future orders. This $1 falls off of your account automatically.
