Needed a set of Blum hinges to replace a broken one on a Sunday, but not sure about the ones produced. Andy in the Brighouse store went that extra mile & suggested I call back before 4:30 closing time to see if he'd managed to find some. I called back & I asked if he'd managed to find a pair, he rattled the cellophane wrapper containing a correct pair. Half an hour later, job done. Well done Screwfix.
