Saw this in O2 Priority App this morning and thought it would be worth a share. Not sure if it works for new customers.
Can be redeemed online and instore, just choose via the Priority App.
50% off the upfront cost of a tablet bought on a 24 month O2 refresh contract.
This also stacks with the other offer that is currently running for existing O2 customers where you get 20% off the airtime plan when you take a tariff with 3GB+ of data. You can get 5GB of Data for the price of 3GB for example.
Note: Offer is not applicable to the 2018 9.7" iPad
