Many of us use them for utility bills, health insurance etc. (where you can overpay), to buy things below 250 dollars and use the balance to reload Amazon or use PayPal to split payment between 2 cards.

I have a spreadsheet that has

• Date purchased
• Card number
• CVV
• Expiration dates
• Original balance
• Current balance
• Use (comment field where I write what I used it for)
