Hi ****,
Thank you for contacting Apple about the App Store. We're so glad you're interested in this new offering. My name is Natalie and I am delighted to assist you today!
Due to tax laws and commerce restrictions for software in Canada, customers residing in Canada may only purchase games and applications using a credit card.
I'm sorry ****, but you will not be able to purchase games or applications with store credit or an iTunes Gift Card in Canada.
If you have any other concerns surrounding this, feel free to include them in your reply and I'll do my best to assist you.
Again, I apologize for this disappointment ****, I hope that you continue to enjoy the iTunes Store.
It has been my pleasure assisting you. If I can further assist you in any way, you can always reach me for support Sunday-Thursday from 6 a.m to 3 p.m. Pacific Daylight Time.
Your feedback is greatly appreciated ****. You may be receiving an Apple Customer Service survey email in 3 to 5 days. Please feel free to leave comments of your experience with my assistance. Take care and have an excellent day!
Yours Faithfully,
Natalie
iTunes Store Customer Support, CA
