Has anyone tried buying iTunes Gift Cards at whatever % off they can find and then used the credit in the Mac App Store to buy Apple Software? I'm planning on buying Logic Pro X and a 20-25% iTunes discount would make for a pretty hefty saving on the software cost.
This FAQ https://support.apple.com/en-au/HT202152 suggests that you should be able to but I don't want to buy cards only to find there is a fine-print I'm missing.
Cheers
iTunes balance applies to the Mac App Store too. So you will be good.
