I briefly mentioned that I was now accepting donations via Paypal. When I log in my Paypal account I'm greeted with the following message about a promotion they're running with iTunes.
Good news: You can now use PayPal to securely and easily buy music from the massive iTunes catalogue, including lots of exclusive tracks and videos.
But you won't have to buy all your music. For a limited time, when you start using PayPal with your new, free iTunes account, you'll get five songs free (while supplies last).
I'm baffled by the "while supplies last" caveat. If these songs are downloadable digital files, isn't their supply infinite? There's nothing tangible here, with a single file they can create thousands more quite easily. Hell, they can send me one and I'll send them a couple of hundred back moments later. How can they run out of such supplies?
