There's a lot of different offers from various stores and differing comments on what the actual discounts are.
Happy to sign up (then cancel) for a new number on a plan if it's the cheapest way.
I also have an old unused pixel 7 pro I can trade in.
Any help would be greatly appreciated
I'd wait a few weeks after launch, you'll save yourself far more based on all the previous Pixel launches and discounting that goes on.
