All contest payments are processed by our payment processor Stripe (stripe.com) through a secure (SSL, PCI-Compliant) connection.
Users can donate using all major credit cards (Visa, MasterCard, American Express, Discover, Diner's Club) and Visa and MasterCard debit cards.
You will pay a special negotiated credit card processing fee of a flat 2.75% per transaction. (Many other platforms charge the standard rate of 2.9% + 30¢ per transaction).
This fee is automatically deducted, along with our fees, when the donation is deposited into your Stripe account. This means that there is no additional invoicing or paperwork involved.
