Yes, you can. When you check out/are ready to pay, your account balance will show up as a payment option.
I‘m speaking from experience. I purchased a 4th gen 12.9“ iPad Pro yesterday, and I had $100 Apple gift card in my Apple account. When I was checking out, the $100 showed up. Apple asked me whether I’d like to use it, and I did.
@Del Martes. Thanks. I had a virtual Apple Gift Card from Phobio. I redeemed it and it went into my Apple Account Balance. I assume I can still use it as you suggest?
