How good is to have iTunes Store available 24/7 at our entire convenience, huh? Picking only the songs, TV episodes and movies which we love the most with a small price and instant delivery is the entertainment dream coming true. It's even more satisfying when you get them by a reduced price by buying gift certificates here on eBay for a great discount. However, be careful not to spend all of your credits all at once! Spend gradually and proceed with the next purchase only when you finish downloading the previous one.

The reason is that, when you log at iTunes Store with your account, there is a connection time which might last more or less, depending on the number of pending downloads you have. For every computer, there is a limit for such connection time (it depends on how your firewall protection is configured or other certain network settings are done) and the more pending downloads you have, the more time will be needed for connection, and if this time exceeds what's configured on your computer settings, you will simply not be able to download any of your files. I'm having problems to download my pending 120 files on my computer (that's five entire TV seasons) so I had to switch the file transfer process to another computer with more modest system settings.

Bottom Line: Unless you have reasonable computer skills to overcome this constraint, make your purchases in small quantities and download your files one at a time. Don't hurry and have fun!
