O2 Express Delivery is now available on O2 websites, and customers can book and track delivery using the O3 app.

The app is now live on the UK’s O2 sites, but is limited to delivery of a maximum of two orders per day.

The O3 website also offers delivery options for other online retailers, such as Amazon.

Delivery can be tracked with a phone call or through the app, and O3 also offers the option to order online.

Amazon is one of the biggest online retailers in the UK, with more than 30,000 stores, with an online store for all O2 services.

Amazon has not confirmed that the O4 app will be used by customers to track their Uber deliveries, but has said that “every order is tracked and logged in our systems”.

O2’s O3 service is available in all major cities across the UK and the US.
