Lost and Amazon Happy to Replace with 2-day Shipping.
I have now bought 6 of these style items and all were great.  I would add the answer to my own question.  What happens if you lose an Amazon gift card?  I lost 2 of these in my basement (hiding them from the kids - which obviously didn't work out.  Amazon sent me replacement cards in 2 days (Prime) with no hassle.  Had to provide my order numbers and make a request to Amazon service through an email.  The email MUST come from your Prime email.
