Do I have to pay sales tax?
As our headquarters are located in the state of South Carolina, only residents located in South Carolina have to pay sales tax. No customers in any other state or country are required to pay sales tax.
Why was my credit card declined?
If your credit or debit card is declined, you will receive a message notifying you of this when trying to purchase using our online system. When you submit your order, your credit card is securely transmitted and processed by one of the world’s largest payment processors, Authorize.net.
If you receive a message that your card is declined, it’s probably due to one of the following reasons:
- Insufficient balance
- Wrong card number (typo)
- Wrong expiration date (typo)
- New card has not yet been activated
- Card is temporarily suspended or frozen by your bank
Unfortunately, we are not able to provide much assistance if your credit card has been declined. If your card is declined, the best thing to do would be to contact your issuing bank and try to find out why.
