After months of leaks, rumors and teasers the OnePlus 7 and OnePlus 7 Pro have now been announced, and as impressive as the latter is it’s also expensive by OnePlus standards. But it’s possible to soften the blow, as the company will let you trade in an old phone towards either model.

Exactly which handsets you can trade seems to vary by country – when it comes to previous OnePlus phones for example you can reportedly trade any in if you’re in the US, but in the UK you only seem to be able to go back as far as the OnePlus X.
