Easy and useful !!!
Frequently I receive Visa gift cards (with limited expiration date) for my work.  I used to use them in different places, but always is hard to spend the last small balances.  I decided to transfer the small balances to a Amazon Gift card.  It was very simple.  So, now, I can buy items with that balances (and complete with my credit card).  Evermore, I'm transferring the total balances of new Visa gift cards to Amazon, so I don't worry about the Visa's expiration date.
