Microsoft 365 features that help users manage their subscriptions, account settings, and billing information.
You can purchase it directly from Microsoft, through the Apple App Store, or from third-party retailers such as Amazon or Best Buy. Prices, promotions, taxes, and whether the purchase is monthly recurring or a prepaid annual subscription can differ depending on the provider and country. For example, an App Store purchase is billed and automatically renewed through Apple, while a subscription purchased directly from Microsoft is billed and managed by Microsoft. Some retailer purchases are prepaid codes rather than automatic monthly subscriptions. Therefore, if your main concern is the monthly cost, I recommend comparing Microsoft's current price with the price shown by Apple or an authorized retailer in your country before purchasing.
Also take into consideration that the same subscription used for a Windows device will allow you to use it on Mac\Android\iOS
