You can use MasterCard gift cards to make pledges. They act like a debit/credit card when it’s actually a gift card with a predetermined amount of money. Also, there are no fees associated with this card as long as you use all the money up within a year of purchase. Here’s how to use it for a Kickstarter Pledge.
1. Go to your local grocery store (Vons, Ralphs, Albertsons).
2. Pick up a MasterCard gift card for 25-100 dollars.
3. Follow the instructions on the card to register it online before making your Pledge.
4. Use it on Amazon Payments through Kickstarter to make your pledge as if it was a debit/credit card.
