Can i use paypal to pay for my iCloud storage?

Gianricofromcarmignano,

According to: Payment methods you can use in the iTunes Store, App Store, and iBooks Store - Apple Support

The available payment methods vary by country. You can typically use these methods:

• Credit cards
• Debit cards
• Content codes
• Store credit, including iTunes Store Gift Cards, Gift Certificates, and Allowances
• PayPal (requires the account to be linked to a credit card)
• China UnionPay (requires SMS PIN for setup)
• Mobile phone billing (through supported carriers)
• Bank Cards (China only)¹

You can use an iTunes store credit, a credit card or a debit card. If you can only use Paypal, purchase an iTunes gift card with it and redeem the card to create and iTunes store credit. Your storage purchase will be deducted from the iTunes store credit and will only charge a credit or debit card if the credit is insufficient to cover the charge.
