I received an email stating that my credit card has been declined. What should I do?

A declined card could mean several things:

1. Incorrect credit card number or expiry date 
2. Insufficient funds 
3. Some banks will reject charges based on location 
4. Some banks will reject charges based on their own fraud rules
   

If a decline keeps happening, it would be best to check with your bank or credit card issuer regarding the matter, or try a different credit card for payment.
