It's a gift card reload - not rocket science
I keep a little cash on my Amazon gift card.  I buy 2 or 3 inexpensive books each week ($0.99 - $1.99).  It's easier to put $50 or $100 on the card than keep track of credit or debit card charges that are small and ofteen.<br /><br />What puzzles me is why this would warrant a review.
