Cheapest I've seen this. Not entirely sure what grade it actually is as they show a sealed box, grade B in the title and grade A in the description but knowing Currys_clearance it will probably arrive like new with original accessories. Even grade B devices I've had from them often turned up spotless with original box.
Currys_clearance on eBay have very good responsive customer services and returns are easy if unhappy. Massive saving over the 2021 M1 model but virtually no compromises.
