In some cases participants will run into a situation where their debit or credit cards are being declined, even in cases where there are sufficient funds.
Chances are your bank is triggering this for a variety of security reasons:
- You're making a large online purchase
- You're making a purchase from a foreign country (we are US based)
To get around this, contact your bank or credit card company and let them know you're trying to make such purchase and they will authorize the payment.
