Other iPhone upgrade programme process in UK?

[bolyki01]

Hi

I had the iUP before, but it was when it first came out, like iPhone 5 era or something.

Now I went to the app, got approved finance with Barclays.

Question is, is it only available for in store pickup? If yes, how long will I be able to stay put to pick it up? I am out of the UK until 26th and I wonder if they keep it.

Would it be available for delivery?

Thanks
