Why did I get billed twice this month?
It is very likely one invoice is for your monthly hosting fees, and the other is for your yearly domain registration fees. Each invoice and/or sales receipt always has very detailed line items stating what each charge is for. You will see line items like: YOURDOMAIN - Hosting Monthly -or- YOURDOMAIN - Domain Registration.
Please feel free to call or email or our support or billing departments if you have any questions though - we are always glad to help out!
