PayPal must not have been content to let you add pre-paid gift cards to your digital wallet, because now it's selling them directly. The online-payment juggernaut is kicking off this new program (dubbed PayPal Digital Gifts) with none other than iTunes, whose digital gift certificates come in $15, $25, $50 and $100 denominations. With this, the firm hopes to streamline online gift-card giving while adding its trademark layer of security for good measure. The company admits the digital storefront is a bit sparse at the moment, but says it will be announcing more partners soon. Unfortunately, the offer is only available in the US, space tourists will have to shop elsewhere.
