How to add Pre-Pay for your account. This can be very useful if you expect to be travelling or unavailable to login and pay for future account renewals and would rather keep a positive balance rather than enabling automatic renewals. 

1)Go to http://pay.arvixe.com/
2)Replace 0.00 with a custom value of how much you want to pay. For example, if you have a Personal Class account that is $7 monthly and you want to pre-pay for 3 months, you put a value of "21" without quotes and click "Next" and click any payment method you want and proceed.  (Image below)

3)There you go! Now when your Hosting Account is about to renew, it will take credit from your account.
