It just doesn't work. A few years ago, I bought a couple of iTunes gift cards for family members. I have one of them sitting in front of me and wanted to see if it has a balance. A miserable waste of an hour later, I have the answer. You can't just check the balance of an iTunes gift card on a web site. Nope. Not possible. I tried www.apple.com/shop/gift-cards and clicked 'Check balance.' It won't let me check the balance w/o signing in to my account. What? It's a plastic gift card! I didn't purchase it with an Apple ID -- I shouldn't be required to use an Apple ID to find out if it has a remaining balance. Anyway, I have 3 Apple IDs in my house. I pick one, log in, and am asked for a PIN. There are 4 sets of numbers on the back of the card, but I assume it's the one that was under the scratch-off. The response - invalid PIN. Great. I try the other 3 sets of numbers and get the same response. After more Googling for suggestions to figure this out, I decide to call Apple Support. Their robot asks why I'm calling. "Gift Card Balance." More questions, like my Apple ID, which device am I calling about, and what's the device serial number. Come on! Seriously? I ask the robot if I can talk to a real person and get transferred. The nice lady hems and haws, puts me on hold for 5 minutes, then decides she needs to transfer me to an iTunes person. 2 more minutes and the iTunes person answers. The nice iTunes lady asks for my Apple ID. Sigh...I interrupt her and ask why she needs that -- I have a physical, plastic iTunes card and want to know if it has a balance. Yes. She says she can help. Finally, after figuring out which of the numbers she needs and repeating the string a couple of times, she responds, "the card has been redeemed." "Redeemed? Okay, great. Do you realize I just wasted an hour only to find out my card has a zero balance?" "I didn't say it has a zero balance - I said it was redeemed." Huh? What does that mean? It basically means that the gift card balance was transferred to an Apple account. There is still money available, but it's on the account. "Which one? How much?" "I can't tell you that." Sigh.... Thanks, Apple.
