Sadly depending on the manufacturer, some won't accept them back and it's the shops loss. Sure somebody from ocuk said once there is a skip full of smashed up high end monitors costing hunderds of pounds each
Of course they dont want them back there crap lol and they know this when they sell them pity they wernt put in skip after qc , oh wait there is no qc so lets ofload them to the consumer they wont suspect a thing.
cue evil corporate laugh ...... muhahaha
