Maintain a small Amazon.com gift card balance to pay for late night movie rentals on Amazon Prime. Buy an Amazon.com gift card from the Gene Grawe Fund and load its balance into your Amazon gift card account. You can even scan the Claim Code with your smartphone’s Amazon App. Then try to remember to not let the balance go below $20. That should be enough to cover most Amazon Prime movie rentals.

Unless you change it in your Amazon.com settings, purchase payments will always come from your Amazon.com gift card balance before Amazon makes a charge to any of your credit or debit cards on file.

I always found it very aggravating when a Prime movie rental showed up on my credit card bill. When it comes to the Gene Grawe Fund, it’s just like that old saying, “Take care of the pennies and the dollars will take care of themselves.”
