Q: is it possible to pay for iCloud storage plan with money from iTunes?

Hey LARISAFROMTX,

Thanks for the question. Yes, you can use iTunes Store credit to pay for an iCloud storage upgrade:

Accepted payment methods for iCloud storage upgrades include credit cards, debit cards, and iTunes Store credit. If you don't have enough iTunes store credit to complete your upgrade, you'll be charged the remaining amount. Apple Store gift cards are not accepted as payment for upgrading iCloud storage.
