How can I get rid of cents left on my iTunes account

Option#1:

This link used to have this information but Apple has 'improved' it so it no longer contains this useful tip:

If you can’t change your iTunes Store country or region - Apple Support - https://support.apple.com/HT204447 - "If your store credit is less than the cost of a single item on the iTunes Store, App Store, or iBooks Store, you can add a credit card to your account [https://support.apple.com/kb/HT201266]. When you buy an item, you will use the remaining store credit and charge the remainder of the purchase to your credit card."

Option #2:

"If you don't have a credit card, contact iTunes Store support." Apple will remove the balance and keep it.

Option #3

I haven't heard of anybody trying this but: Create and add money to an iTunes Pass - https://support.apple.com/HT203021 - "With an iTunes Pass, you can add funds to your iTunes account at Apple Stores or select retailers. You can use the funds to buy music, apps, movies, books, or TV shows*." Limited countries only. Add exactly what you need to buy something (don't forget tax, if applicable).

Purchase something inexpensive. The store should use up the 27 cents and then charge your credit card for the remainder.
