Found the perfect gft!
I received an Amazon Gift card and redeemed  it for a ring.  The ring was not quite right, so I returned it.  I was worried because I had thrown the actual gift card away.  Thankfully, I never had to remind Amazon that I had used a gift card, it remembered, and when I finally found exactly what I wanted, the gift card amount was deducted from the cost.  Easy.
