In the UK the Google trade in values are really good. My iPhone 13 mini can be traded in for £480 towards a new Pixel phone. Plus they're throwing in free pair of Pixel buds pro, or the Pixel watch 2 depending on phone model.Not sure if you looked, but if you are upgrading from last years Pixel models, the Google trade in values are garbage. I was on the fence about upgrading my 7 Pro to the 8 Pro, but for $425 in trade in, it is completely not worth it.
I guess I'll be waiting to see what Samsung comes up with in January, then choose between their Ultra and the 15 Pro Max.
It's very tempting to switch over.
