If I was to buy the Xs Max 256gb through Very with the 10% discount, the device total would come to £1,124. If I then chose the 12 month interest free option, I'd choose to pay £50 a month, so at the end of the 12 months the remaining balance would be £530 (£1,124 - (12 x £50)). I'd then sell the phone before upgrading to the new iPhone next year.
Doing the above would technically mean I was only paying just £600 for the new phone over the 12 months. Can anyone see a problem or issue with doing it this way? Seems too good to be true...
