We accept Visa & Discover cards for all purchases, including trials. Mastercard is also accepted for straight sale (one time) purchases but is not accepted for all trials. As such, do not accept Mastercard for payment if you are processing an order over the phone - the customers must place the order themselves via the website.

• Cash on Delivery
• Gift cards
• Bitcoin
• War bonds
• Barter
• Any other form of payment
