Uhm they can, one can buy amazon.com giftcards in any retailer in US and at any coinstar kiosk for cold cash.

Hell one can even buy amazon giftcards using bitcoin via gyft.com and receive 3% bonus back!

If anything its Paypal that is unable to reach as many people as Amazon, and continue to alienate more and more users every day by screwing around with them etc.
