Handy feature that gives you another option
It came in handy when I needed it!  I had purchased a PC online & needed to upgrade an existing component.  At check-out I had an issue with my cc, and just before cancelling my order, I remembered the balance I had.  And the timing was perfect as the item was very limited & missing this order would've added unknown waiting time until it was replenished.  When I first added it, I thought the site pushed the feature a little much, but was very glad I had it when i needed it.  If you shop on the site much at all, it's a great option!
