Do you accept alternate forms of payment aside from credit cards, Google Checkout, or PayPal?

Yes! We can accept purchase orders, checks, and direct bank transfers. Please note that for checks and purchase orders, your order cannot be completed until the payment has cleared our bank. To arrange for payment via one of these methods, please contact us and we’ll be happy to assist you.

Will you send me a sales receipt?

We are happy to send a sales receipt on request. When emailing us to confirm your order, please indicate that you would like a sales receipt, and include the billing contact information that should be included on it (contact name, company name if applicable and address).

What's an x-Credit?

x-Credits are used when creating a Support Ticket. A Support Ticket uses 10 x-Credits per incident. Telephone Support uses 50 x-Credits per hour with a 25 x-Credit minimum. (Premium support forums are available 24/7/365 and do not require x-Credits.)
